bec2f429af Reject operator names >= NAMEDATALEN characters. These will not work
anyway, and in assert-enabled builds you are likely to get an assertion
failure.  Backpatch as far as 7.3; 7.2 seems not to have the problem.

4f142baf37 expandRTE and get_rte_attribute_type mistakenly always imputed typmod -1
to columns of an RTE that was a function returning RECORD with a column
definition list.  Apparently no one has tried to use non-default typmod
with a function returning RECORD before.

5454eb0456 Fix previous patch to exprTypmod. 2005-05-25 02:03:52 +00:00
8f5702ebd5 Inserting 5 characters into char(10) does not produce 5 padding spaces
if they are two-byte multibyte characters. Same thing can be happen
if octet_length(multibyte_chars) == n where n is char(n).
Long standing bug since 7.3 days. Per report and fix from Yoshiyuki Asaba.

263b42f289 Don't generate 'zero' typeids in the output from gen_cross_product.
This is no longer necessary or appropriate since we don't use zero typeid
as a wildcard anymore, and it fixes a nasty performance problem with
functions with many parameters.  Per recent example from Reuven Lerner.

f1b3af29c1 When a TIMESTAMP, TIME, or INTERVAL precision is specified larger than our
implementation limits, do not issue an ERROR; instead issue a NOTICE and use
the max supported value.  Per pgsql-general discussion of 28-Apr, this is
needed to allow easy porting from pre-7.3 releases where the limits were
higher.

Unrelated change in same area: accept GLOBAL TEMP/TEMPORARY as a synonym
for TEMPORARY, as per pgsql-hackers discussion of 15-Apr.  We previously
rejected it, but that was based on a misreading of the spec --- SQL92's
GLOBAL temp tables are really closer to what we have than their LOCAL ones.

60bc45a107 Fix misbehavior of func_error() on type names containing '%'.
Will patch separately but equivalently in HEAD.

19f60754e1 Remove premature attempt to constant-fold type coercion expressions.
While usually safe, this fails if the coercion function needs the
query snapshot to be set already.  Per example from Nigel Andrews.

a880697f09 Repair incorrect checking of grouped/ungrouped variables in the presence
of unnamed joins; per pghackers discussion 31-Mar-03.

c6d801f3bf Parser was dropping foreign-key constraints on the floor if present in
an ALTER TABLE ADD COLUMN command.  Per bug #896.

02c614dc85 Use a varno not chosen at random for dummy variables in the top-level
targetlist of a set-operation tree.  I'm not sure that this solution
will really stand the test of time --- perhaps we need to make a special
RTE for such vars to refer to.  But this quick hack fixes Brandon Craig
Rhodes' complaint of 10-Feb-02 about EXCEPT in CREATE RULE, while not
changing any behavior in the better-tested cases where leftmostRTI is
one anyway.
2003-02-11 04:13:39 +00:00
47729caf2d Allow qualified type names in CREATE CAST, DROP CAST. Also allow the
construction 'SETOF type[]' which for some reason was previously
overlooked (you'd have to name the array type directly to make it work).

b52fe8dcc8 Tweak bison build rules so that we get the same error messages from
bison 1.875 and later as we did from earlier bison releases.  Eventually
we will probably want to adopt the newer message spelling ... but not yet.
Per recent discussion on pgpatches.
Note: I didn't change the build rules for bootstrap, ecpg, or plpgsql
grammars, since these do not affect regression test results.

b37d6373f0 Deliver better error message when a relation name is used in an expression.
Per report from Ian Barwick.

f599d56f51 Fix ALTER TABLE ADD COLUMN to disallow the same column types that are
disallowed by CREATE TABLE (eg, pseudo-types); also disallow these types
from being introduced by the range-function syntax.  While at it, allow
CREATE TABLE to create zero-column tables, per recent pghackers discussion.
I am back-patching this into 7.3 since failure to disallow pseudo-types
is arguably a security hole.

cab9437a43 Arrange to compile flex output files as inclusions into other files
(usually bison output files), not as standalone files.  This hack
works around flex's insistence on including <stdio.h> before we are
able to include postgres.h; postgres.h will already be read before
the compiler starts to read the flex output file.  Needed for largefile
support on some platforms.

c3086c8f53 Function-call-style type coercions should be treated as explicit
coercions, not implicit ones.  For example, 'select abstime(1035497293)'
should succeed because there is an explicit binary coercion from int4
to abstime.

200b151615 Fix places that were using IsTransactionBlock() as an (inadequate) check
that they'd get to commit immediately on finishing.  There's now a
centralized routine PreventTransactionChain() that implements the
necessary tests.

d508b057ac Adjust handling of command status strings in the presence of rules,

6d0d15c451 Make the world at least somewhat safe for zero-column tables, and
remove the special case in ALTER DROP COLUMN to prohibit dropping a
table's last column.

9946b83ded Bring SIMILAR TO and SUBSTRING into some semblance of conformance with
the SQL99 standard.  (I'm not sure that the character-class features are
quite right, but that can be fixed later.)  Document SQL99 and POSIX
regexps as being different features; provide variants of SUBSTRING for
each.

ac355d558e Move most of the error checking for foreign-key constraints out of
parse analysis and into the execution code (in tablecmds.c).  This
eliminates a lot of unreasonably complex code that needed to have two
or more execution paths in case it was dealing with a not-yet-created
table column vs. an already-existing one.  The execution code is always
dealing with already-created tables and so needs only one case.  This
also eliminates some potential race conditions (the table wasn't locked
between parse analysis and execution), makes it easy to fix the gripe
about wrong referenced-column names generating a misleading error message,
and lets us easily add a dependency from the foreign-key constraint to
the unique index that it requires the referenced table to have.  (Cf.
complaint from Kris Jurka 12-Sep-2002 on pgsql-bugs.)

Also, third try at building a deletion mechanism that is not sensitive
to the order in which pg_depend entries are visited.  Adding the above-
mentioned dependency exposed the folly of what dependency.c had been
doing: it failed for cases where B depends on C while both auto-depend
on A.  Dropping A should succeed in this case, but was failing if C
happened to be visited before B.  It appears the only solution is two
separate walks over the dependency tree.

b26dfb9522 Extend pg_cast castimplicit column to a three-way value; this allows us
to be flexible about assignment casts without introducing ambiguity in
operator/function resolution.  Introduce a well-defined promotion hierarchy
for numeric datatypes (int2->int4->int8->numeric->float4->float8).
Change make_const to initially label numeric literals as int4, int8, or
numeric (never float8 anymore).
Explicitly mark Func and RelabelType nodes to indicate whether they came
from a function call, explicit cast, or implicit cast; use this to do
reverse-listing more accurately and without so many heuristics.
Explicit casts to char, varchar, bit, varbit will truncate or pad without
raising an error (the pre-7.2 behavior), while assigning to a column without
any explicit cast will still raise an error for wrong-length data like 7.3.
This more nearly follows the SQL spec than 7.2 behavior (we should be
reporting a 'completion condition' in the explicit-cast cases, but we have
no mechanism for that, so just do silent truncation).
Fix some problems with enforcement of typmod for array elements;
it didn't work at all in 'UPDATE ... SET array[n] = foo', for example.
Provide a generalized array_length_coerce() function to replace the
specialized per-array-type functions that used to be needed (and were
missing for NUMERIC as well as all the datetime types).
Add missing conversions int8<->float4, text<->numeric, oid<->int8.
initdb forced.

6fe27ca2fb Fix some operator-precedence problems. New constructs IS DISTINCT FRM
and IS [NOT] OF were not being parsed consistently with other IS forms.
Also, make the world a little safer for functions named LEFT, RIGHT, etc.

52c9d25933 Be careful to include postgres.h *before* any system headers, to ensure
that the right flavors of largefile-related definitions are seen.
Most of these changes are probably unnecessary, but better safe than
sorry.

a12b4e279b I checked all the previous string handling errors and most of them were
already fixed by You. However there were a few left and attached patch
should fix the rest of them.

I used StringInfo only in 2 places and both of them are inside debug
ifdefs. Only performance penalty will come from using strlen() like all
the other code does.

I also modified some of the already patched parts by changing
snprintf(buf, 2 * BUFSIZE, ... style lines to
snprintf(buf, sizeof(buf), ... where buf is an array.

845a6c3acc Code review for domain-constraints patch. Use a new ConstraintTest node
type for runtime constraint checks, instead of misusing the parse-time
Constraint node for the purpose.  Fix some damage introduced into type
coercion logic; in particular ensure that a coerced expression tree will
read out the correct result type when inspected (patch had broken some
RelabelType cases).  Enforce domain NOT NULL constraints against columns
that are omitted from an INSERT.

81dfa2ce43 backend where a statically sized buffer is written to. Most of these
should be pretty safe in practice, but it's probably better to be safe
than sorry.

I was actually looking for cases where NAMEDATALEN is assumed to be
32, but only found one. That's fixed too, as well as a few bits of
code cleanup.

from Tom Lane.

dd912c6977 This patches replaces a few more usages of strcpy() and sprintf() when
copying into a fixed-size buffer (in this case, a buffer of
NAMEDATALEN bytes). AFAICT nothing to worry about here, but worth
fixing anyway...

5cabcfccce Modify array operations to include array's element type OID in the
array header, and to compute sizing and alignment of array elements
the same way normal tuple access operations do --- viz, using the
tupmacs.h macros att_addlength and att_align.  This makes the world
safe for arrays of cstrings or intervals, and should make it much
easier to write array-type-polymorphic functions; as examples see
the cleanups of array_out and contrib/array_iterator.  By Joe Conway
and Tom Lane.

b663f3443b Add a bunch of pseudo-types to replace the behavior formerly associated
with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

a0bf1a7f2e Fix pg_dump to dump serial columns as serials. Per pghackers discussion,
cause SERIAL column declaration not to imply UNIQUE, so that this can be
done without creating an extra index.

6ebc90b045 Remove Ident nodetype in favor of using String nodes; this fixes some
latent wrong-struct-type bugs and makes the coding style more uniform,
since the majority of places working with lists of column names were
already using Strings not Idents.  While at it, remove vestigial
support for Stream node type, and otherwise-unreferenced nodes.h entries
for T_TupleCount and T_BaseNode.
NB: full recompile is recommended due to changes of Node type numbers.
This shouldn't force an initdb though.
2002-08-19 15:08:47 +00:00
22bfa72068 Remove optimization whereby parser would make only one sort-list entry
when two equal() targetlist items were to be added to an ORDER BY or
DISTINCT list.  Although indeed this would make sorting fractionally
faster by sometimes saving a comparison, it confuses the heck out of
later stages of processing, because it makes it look like the user
wrote DISTINCT ON rather than DISTINCT.  Bug reported by joe@piscitella.com.

c828ec8820 Make pg_dump output more portable and more pleasing to look at.
The -n and -N options were removed.  Quoting is now smart enough to
supply quotes if and only if necessary.

Numerical types are now printed without quotes, except in cases of
special values such as NaN.

Boolean values printed as true and false.

Most string literals now do not escape whitespace characters (newlines,
etc.) for portability.

SET SESSION AUTHORIZATION argument is a string literal, to follow SQL.

Made commands output by pg_dump use consistent spacing and indentation.
