> * -Add function to return compressed length of TOAST data values

find myself typing a command and then wanting to get the syntax for it.
So I do a ctrl-a and add a \h: but psql does not recognize the command,
because I have stuff attached to it (e.g. "alter table foobar"), so I
have to scroll over and delete everything except the name of the command
itself. This patch gives \h three chances to match: if nothing matches
the complete string (current behavior), it tries to match the first two
words (e.g. "ALTER TABLE"). If that fails, it tries to match the first
word (e.g. "DELETE").

just opens file timestamp skew problems without doing anything useful.

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

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.

Now openssl.c just checks OpenSSL version.  Whoever compiles
newer OpenSSL without AES is on his own.
