This patch allows the PL/Python module to do (SRF) functions.
The patch was taken from the CVS version.
I have modified the plpython.c file and have added a test sql script for
testing the functionality. It was actually the script that was in the
8.0.3 version but have since been removed.
In order to signal the end of a set, the called python function must
simply return plpy.EndOfSet and the set would be returned.

The content of the patch is as follows:
(1)Create shortcut when subtext was not found.
(2)Stop using LEFT and RIGHT macro.
In LEFT and RIGHT macro, TEXTPOS is executed by the same content as
execution immediately before. The execution frequency of TEXTPOS can be
reduced by using text_substring instead of LEFT and RIGHT macro.
(3)Add appendStringInfoText, and use it instead of
appendStringInfoString.
There is an overhead of PG_TEXT_GET_STR when appendStringInfoString is
executed by text type. This can be reduced by appendStringInfoText.
(4)Reduce execution of TEXTDUP.
The effect of the patch that I measured is as follows:
- The Data for test was created by 'pgbench -i'.
- Test SQL:
select replace(aid, '9', 'A') from accounts;
- Test results: Linux(CPU: Pentium III, Compiler option: -O2)
original: 1.515s
patched: 1.250s

Backpatch to 8.0.X.

chdir into PGDATA and subsequently use relative paths instead of absolute
paths to access all files under PGDATA. This seems to give a small
performance improvement, and it should make the system more robust
against naive DBAs doing things like moving a database directory that
has a live postmaster in it. Per recent discussion.

You were correct. This patch fixes it.

able to do this before, but I had tried to make an exception for functions
with OUT parameters. Michael Fuhr found one problem with it already, and
I found another, which was it didn't work for strict functions with a
NULL input. While both of these could be worked around, the probability
that there are more gotchas seems high; I think prudence dictates just
reverting to the former behavior for now. Accordingly, remove the kluge
added to get_expr_result_type() for Michael's case.

relies on the output of zic being platform independent, but that is
currently the case.

propagated inside an outer join. In particular, given
LEFT JOIN ON (A = B) WHERE A = constant, we cannot conclude that
B = constant at the top level (B might be null instead), but we
can nonetheless put a restriction B = constant into the quals for
B's relation, since no inner-side rows not meeting that condition
can contribute to the final result. Similarly, given
FULL JOIN USING (J) WHERE J = constant, we can't directly conclude
that either input J variable = constant, but it's OK to push such
quals into each input rel. Per recent gripe from Kim Bisgaard.
Along the way, remove 'valid_everywhere' flag from RestrictInfo,
as on closer analysis it was not being used for anything, and was
defined backwards anyway.

basic regression tests for GiST to the standard regression tests.
I took the opportunity to add an rtree-equivalent gist opclass for
circles; the contrib version only covered boxes and polygons, but
indexing circles is very handy for distance searches.

non-NULL in this function, so there is no need to check for it (2) we
should check the return value of pgtypes_strdup(). Patch from Eric
Astor at EnterpriseDB, with slight cleanup by myself, per a report
from the Coverity tool.

- remove level of pages: hard to check in recovery
- some cleanups

or zero-filled; therefore zero-filling it via memset() is pointless.
(I think setting `errno' is probably a waste of cycles as well, but I
haven't changed that.)

remove old-style function declarations, and mark a function "static".
There are some remaining warnings, but this fixes most of them, anyway.

malloc() succeeded but the second failed, the buffer allocated by the
first malloc() would be leaked. Fix this by allocating both buffers
via a single malloc(), as suggested by Tom.

the difference between checkpoints forced due to WAL segment consumption
and checkpoints forced for other reasons (such as CREATE DATABASE). Avoid
generating 'checkpoints are occurring too frequently' messages when the
checkpoint wasn't caused by WAL segment consumption. Per gripe from
Chris K-L.

current time: provide a GetCurrentTimestamp() function that returns
current time in the form of a TimestampTz, instead of separate time_t
and microseconds fields. This is what all the callers really want
anyway, and it eliminates low-level dependencies on AbsoluteTime,
which is a deprecated datatype that will have to disappear eventually.

role memberships; make superuser/createrole distinction do something

In particular, make hba.c cope with zero-length tokens, which it
never did properly before. Also, enforce rolcanlogin.
|
|
syntactic conflicts, both privilege and role GRANT/REVOKE commands have
to use the same production for scanning the list of tokens that might
eventually turn out to be privileges or role names. So, change the
existing GRANT/REVOKE code to expect a list of strings not pre-reduced
AclMode values. Fix a couple other minor issues while at it, such as
InitializeAcl function name conflicting with a Windows system function.
