320b6db090 Changes from Vince Vielhaber to allow the optional clauses of CREATE
USER and ALTER USER to appear in any order, not only the fixed order
they used to be required to appear in.
Also, some changes from Tom Lane to create a FULL option for VACUUM;
it doesn't do anything yet, but I needed to change many of the same
files to make that happen, so now seemed like a good time.

to wait until it's safe to remove tuples and compact free space in a
shared buffer page.  Miscellaneous small code cleanups in bufmgr, too.

30ab5bd43d More message munging and localization for pg_dump, especially the
--verbose messages, which had not been considered so far.  Output to the
terminal should okay now; comments written into the dump are still English
only, which may or may not be the desirable thing.

42748087c1 First non-stub implementation of shared free space map. It's not super
useful as yet, since its primary source of information is (full) VACUUM,
which makes a concerted effort to get rid of free space before telling
the map about it ... next stop is concurrent VACUUM ...

201aa35d2f gcc did not like new pg_stat macros, for good and sufficient reason.
Add 'do { ... } while (0)' decoration to eliminate compiler warnings.
2001-06-29 23:03:02 +00:00
af5ced9cfd Further work on connecting the free space map (which is still just a
stub) into the rest of the system.  Adopt a cleaner approach to preventing
deadlock in concurrent heap_updates: allow RelationGetBufferForTuple to
select any page of the rel, and put the onus on it to lock both buffers
in a consistent order.  Remove no-longer-needed isExtend hack from
API of ReleaseAndReadBuffer.

e0c9301c87 Install infrastructure for shared-memory free space map. Doesn't actually
do anything yet, but it has the necessary connections to initialization
and so forth.  Make some gestures towards allowing number of blocks in
a relation to be BlockNumber, ie, unsigned int, rather than signed int.
(I doubt I got all the places that are sloppy about it, yet.)  On the
way, replace the hardwired NLOCKS_PER_XACT fudge factor with a GUC
variable.

4d58a7ca87 Optimizer can now estimate selectivity of IS NULL, IS NOT NULL,
IS TRUE, etc, with some degree of verisimilitude.  Split out
selectivity support functions from builtins.h into a new header
file selfuncs.h, so as to reduce the number of header files builtins.h
must depend on.  Fix a few missing inclusions exposed thereby.

d8d9ed931e Add support to lock manager for conditionally locking a lock (ie,

9b4bfbdc2c Handle reading of startup packet and authentication exchange after forking
a new postmaster child process.  This should eliminate problems with
authentication blocking (e.g., ident, SSL init) and also reduce problems
with the accept queue filling up under heavy load.

The option to send elog output to a different file per backend (postgres -o)
has been disabled for now because the initialization would have to happen
in a different order and it's not clear we want to keep this anyway.

8c30aca2ba Fix badly broken RelationGetRelationName(). 2001-06-19 21:28:41 +00:00
bbbc00af88 Clean up some longstanding problems in shared-cache invalidation.
SI messages now include the relevant database OID, so that operations
in one database do not cause useless cache flushes in backends attached
to other databases.  Declare SI messages properly using a union, to
eliminate the former assumption that Oid is the same size as int or Index.
Rewrite the nearly-unreadable code in inval.c, and document it better.
Arrange for catcache flushes at end of command/transaction to happen before
relcache flushes do --- this avoids loading a new tuple into the catcache
while setting up new relcache entry, only to have it be flushed again
immediately.

558fae16e3 The attached patch enables the contrib subtree to build cleanly under
Cygwin with the possible exception of mSQL-interface.  Since I don't
have mSQL installed, I skipped this tool.

Except for dealing with a missing getopt.h (oid2name) and HUGE (seg),
the bulk of the patch uses the standard PostgreSQL approach to deal with
Windows DLL issues.

I tested the build aspect of this patch under Cygwin and Linux without
any ill affects.  Note that I did not actually attempt to test the code
for functionality.

The procedure to apply the patch is as follows:

    $ # save the attachment as /tmp/contrib.patch
    $ # change directory to the top of the PostgreSQL source tree
    $ patch -p0 </tmp/contrib.patch

2c5aa2acb4 Do some restructuring to improve performance of the catcaches. Teach
CatalogCacheFlushRelation (formerly called SystemCacheRelationFlushed)
how to distinguish tuples it should flush from those it needn't; this
means a relcache flush event now only removes the catcache entries
it ought to, rather than zapping the caches completely as it used to.
Testing with the regression tests indicates that this considerably
improves the lifespan of catcache entries.  Also, rearrange catcache
data structures so that the limit on number of cached tuples applies
globally across all the catcaches, rather than being per-catcache.
It was a little silly to have the same size limit on both, say,
pg_attribute caches and pg_am caches (there being only four possible
rows in the latter...).  Doing LRU removal across all the caches
instead of locally in each one should reduce cache reload traffic
in the more heavily used caches and improve the efficiency of
cache memory use.

1f1ca182be Make inet/cidr << and <<= operators indexable. From Alex Pilosov <alex@pilosoft.com>. 2001-06-17 02:05:20 +00:00
2917f0a5dd Tweak startup sequence so that running out of PROC array slots is
detected sooner in backend startup, and is treated as an expected error
(it gives 'Sorry, too many clients already' now).  This allows us not
to have to enforce the MaxBackends limit exactly in the postmaster.
Also, remove ProcRemove() and fold its functionality into ProcKill().
There's no good reason for a backend not to be responsible for removing
its PROC entry, and there are lots of good reasons for the postmaster
not to be touching shared-memory data structures.
2001-06-16 22:58:17 +00:00
668db147d5 It turns out that the relcache thinks it can distinguish different
rules and triggers by OID.  So, even though we have no cross-references
in the system catalogs to pg_rewrite.oid or pg_trigger.oid, we'd better
have unique indexes on them.  Put back pg_rewrite_oid_index, which I
mistakenly removed a few days ago, and add pg_trigger_oid_index.

c9499e68da has_table_privilege functions from Joe Conway (with some kibitzing from

1a6bb6d877 Allow a non-superuser database owner to vacuum all tables in his
database, including system catalogs (but not the shared catalogs,
since they don't really belong to his database).  This is per recent

for database ownerness by introducing a test function is_dbadmin().

bbb7b6f699 Remove some dead code, simplify calling convention. 2001-06-13 18:56:30 +00:00
2938eec7fe Extend GUC concepts of parse_hook and assign_hook to all four supported
datatypes, not only strings.  parse_hook is useless for bool, I suppose,
but it seems possibly useful for int and double to apply variable-specific
constraints that are more complex than simple range limits.  assign_hook
is definitely useful for all datatypes --- we need it right now for bool
to support date cache reset when changing Australian timezone rule setting.
Also, clean up some residual problems with the reset all/show all patch,
including memory leaks and mistaken reset of PostPortNumber.  It seems
best that RESET ALL not touch variables that don't have SUSET or
USERSET context.

76e9ad1f55 Back out has_table_privilege patch. 2001-06-12 16:34:27 +00:00
58c909bb8d OK -- here's take #5.
It "make"s and "make check"s clean against current cvs tip.

There are now both Text and Name variants, and the regression test support
is rolled into the patch. Note that to be complete wrt Name based variants,
there are now 12 user visible versions of has_table_privilege:

has_table_privilege(Text usename, Text relname, Text priv_type)
has_table_privilege(Text usename, Name relname, Text priv_type)
has_table_privilege(Name usename, Text relname, Text priv_type)
has_table_privilege(Name usename, Name relname, Text priv_type)
has_table_privilege(Text relname, Text priv_type) /* assumes current_user */
has_table_privilege(Name relname, Text priv_type) /* assumes current_user */
has_table_privilege(Text usename, Oid reloid, Text priv_type)
has_table_privilege(Name usename, Oid reloid, Text priv_type)
has_table_privilege(Oid reloid, Text priv_type)  /* assumes current_user */
has_table_privilege(Oid usesysid, Text relname, Text priv_type)
has_table_privilege(Oid usesysid, Name relname, Text priv_type)
has_table_privilege(Oid usesysid, Oid reloid, Text priv_type)

For the Text based inputs, a new internal function, get_Name is used
(shamelessly copied from get_seq_name in sequence.c) to downcase if not
quoted, or remove quotes if quoted, and truncate. I also added a few test
cases for the downcasing, quote removal, and Name based variants to the
regression test.

1d584f97b9 Clean up various to-do items associated with system indexes:
pg_database now has unique indexes on oid and on datname.
pg_shadow now has unique indexes on usename and on usesysid.
pg_am now has unique index on oid.
pg_opclass now has unique index on oid.
pg_amproc now has unique index on amid+amopclaid+amprocnum.
Remove pg_rewrite's unnecessary index on oid, delete unused RULEOID syscache.
Remove index on pg_listener and associated syscache for performance reasons
(caching rows that are certain to change before you need 'em again is
rather pointless).
Change pg_attrdef's nonunique index on adrelid into a unique index on
adrelid+adnum.

Fix various incorrect settings of pg_class.relisshared, make that the
primary reference point for whether a relation is shared or not.
IsSharedSystemRelationName() is now only consulted to initialize relisshared
during initial creation of tables and indexes.  In theory we might now
support shared user relations, though it's not clear how one would get
entries for them into pg_class &etc of multiple databases.

Fix recently reported bug that pg_attribute rows created for an index all have
the same OID.  (Proof that non-unique OID doesn't matter unless it's
actually used to do lookups ;-))

There's no need to treat pg_trigger, pg_attrdef, pg_relcheck as bootstrap
relations.  Convert them into plain system catalogs without hardwired
entries in pg_class and friends.

Unify global.bki and template1.bki into a single init script postgres.bki,
since the alleged distinction between them was misleading and pointless.
Not to mention that it didn't work for setting up indexes on shared
system relations.

Rationalize locking of pg_shadow, pg_group, pg_attrdef (no need to use
AccessExclusiveLock where ExclusiveLock or even RowExclusiveLock will do).
Also, hold locks until transaction commit where necessary.

92f450652c The attached patch enables PostgreSQL CVS to build cleanly under Cygwin
when built against readline 4.2.  Specifically, it handles the deprecation
of

    filename_completion_function()

with preference for

    rl_filename_completion_function()

Although, I was motivated by Cygwin support, IMO this patch is appropriate
for all platforms.  To quote from the readline source:

    #if 0
    /* Backwards compatibility (compat.c).  These will go away sometime. */
    ...
    extern READLINE_EXPORT(char, *filename_completion_function) ...
    #endif

Note that this patch is modeled after the one by Peter Eisentraut for
completion_matches():

    http://www.ca.postgresql.org/~petere/readline42.html
I tested this patch under the following environments:

    Cygwin with readline 4.1
    Cygwin with readline 4.2
    Linux with readline 2.2.1
    Linux with readline 4.2

and it behaved as expected.
