b8da37b3ad Rework pg_input_error_message(), now renamed pg_input_error_info()
pg_input_error_info() is now a SQL function able to return a row with
more than just the error message generated for incorrect data type
inputs when these are able to handle soft failures, returning more
contents of ErrorData, as of:
- The error message (same as before).
- The error detail, if set.
- The error hint, if set.
- SQL error code.

All the regression tests that relied on pg_input_error_message() are
updated to reflect the effects of the rename.

Per discussion with Tom Lane and Andrew Dunstan.

faff8f8e47 Allow underscores in integer and numeric constants.
This allows underscores to be used in integer and numeric literals,
and their corresponding type input functions, for visual grouping.
For example:

    1_500_000_000
    3.14159_26535_89793
    0xffff_ffff
    0b_1001_0001

A single underscore is allowed between any 2 digits, or immediately
after the base prefix indicator of non-decimal integers, per SQL:202x
draft.

6fcda9aba8 Non-decimal integer literals
Add support for hexadecimal, octal, and binary integer literals:

    0x42F
    0o273
    0b100101

per SQL:202x draft.

This adds support in the lexer as well as in the integer type input
functions.

ccff2d20ed Convert a few datatype input functions to use "soft" error reporting.
This patch converts the input functions for bool, int2, int4, int8,
float4, float8, numeric, and contrib/cube to the new soft-error style.
array_in and record_in are also converted.  There's lots more to do,
but this is enough to provide proof-of-concept that the soft-error
API is usable, as well as reference examples for how to convert
input functions.

This patch is mostly by me, but it owes very substantial debt to
earlier work by Nikita Glukhov, Andrew Dunstan, and Amul Sul.
Thanks to Andres Freund for review.

cc50080a82 Rearrange core regression tests to reduce cross-script dependencies.
The idea behind this patch is to make it possible to run individual
test scripts without running the entire core test suite.  Making all
the scripts completely independent would involve a massive rewrite,
and would probably be worse for coverage of things like concurrent DDL.
So this patch just does what seems practical with limited changes.

The net effect is that any test script can be run after running
limited earlier dependencies:
* all scripts depend on test_setup
* many scripts depend on create_index
* other dependencies are few in number, and are documented in
  the parallel_schedule file.

To accomplish this, I chose a small number of commonly-used tables
and moved their creation and filling into test_setup.  Later scripts
are expected not to modify these tables' data contents, for fear of
affecting other scripts' results.  Also, our former habit of declaring
all C functions in one place is now gone in favor of declaring them
where they're used, if that's just one script, or in test_setup if
necessary.

There's more that could be done to remove some of the remaining
inter-script dependencies, but significantly more-invasive changes
would be needed, and at least for now it doesn't seem worth it.

c06d6aa4c3 Clean up ancient test style
Many older tests where written in a style like

    SELECT '' AS two, i.* FROM INT2_TBL

where the first column indicated the number of expected result rows.
This has gotten increasingly out of date, as the test data fixtures
have expanded, so a lot of these were wrong and misleading.  Moreover,
this style isn't really necessary, since the psql output already shows
the number of result rows.

To clean this up, remove all those extra columns.

9d402c73ad Expand tests for factorial
Move from int4 to numeric test.  (They were originally int4 functions,
but were reimplemented for numeric in
04a4821adef38155b7920ba9eb83c4c3c29156f8.)  Add some tests for edge
cases.

06bf0dd6e3 Upgrade src/port/rint.c to be POSIX-compliant.
The POSIX spec says that rint() rounds halfway cases to nearest even.
Our substitute implementation failed to do that, rather rounding halfway
cases away from zero; and it also got some other cases (such as minus
zero) wrong.  This led to observable cross-platform differences, as
reported in bug #12885 from Rich Schaaf; in particular, casting from
float to int didn't honor round-to-nearest-even on builds using rint.c.

Implement something that attempts to cover all cases per spec, and add
some simple regression tests so that we'll notice if any platforms still
get this wrong.

Although this is a bug fix, no back-patch, as a behavioral change in
the back branches was agreed not to be a good idea.

1f7cb5c309 Improve handling of INT_MIN / -1 and related cases.
Some platforms throw an exception for this division, rather than returning
a necessarily-overflowed result.  Since we were testing for overflow after
the fact, an exception isn't nice.  We can avoid the problem by treating
division by -1 as negation.

Add some regression tests so that we'll find out if any compilers try to
optimize away the overflow check conditions.

This ought to be back-patched, but I'm going to see what the buildfarm
reports about the regression tests first.

Per discussion with Xi Wang, though this is different from the patch he
submitted.

815810ed31 Attempt to fix breakage caused by signed integer conversion patch.
Use INT_MIN rather than INT32_MIN as we do elsewhere in the code, and
try to work around nonexistence of INT64_MIN if necessary.  Adjust the
new regression tests to something hopefully saner, per observation by
Tom Lane.

4fc115b2e9 Speed up conversion of signed integers to C strings.
A hand-coded implementation turns out to be much faster than calling
printf().  In passing, add a few more regresion tests.

8d70ed84ba Remove outdated comments from the regression test files.
Since 2004, int2 and int4 operators do detect overflow; this was fixed by
commit 4171bb869f234281a13bb862d3b1e577bf336242.

f5ab0a14ea Add a "USING" clause to DELETE, which is equivalent to the FROM clause
in UPDATE. We also now issue a NOTICE if a query has _any_ implicit
range table entries -- in the past, we would only warn about implicit
RTEs in SELECTs with at least one explicit RTE.

As a result of the warning change, 25 of the regression tests had to
be updated. I also took the opportunity to remove some bogus whitespace
differences between some of the float4 and float8 variants. I believe
I have correctly updated all the platform-specific variants, but let
me know if that's not the case.

Original patch for DELETE ... USING from Euler Taveira de Oliveira,
reworked by Neil Conway.

4171bb869f Detect overflow in integer arithmetic operators (integer, smallint, and
bigint variants).  Clean up some inconsistencies in error message wording.
Fix scanint8 to allow trailing whitespace in INT64_MIN case.  Update
int8-exp-three-digits.out, which seems to have been ignored by the last
couple of people to modify the int8 regression test, and remove
int8-exp-three-digits-win32.out which is thereby exposed as redundant.

e2ded829f6 Revise int2/int4/int8/float4/float8 input routines to allow for
any amount of leading or trailing whitespace (where "whitespace"
is defined by isspace()). This is for SQL conformance, as well
as consistency with other numeric types (e.g. oid, numeric).

Also refactor pg_atoi() to avoid looking at errno where not
necessary, and add a bunch of regression tests for the input
to these types.
