Description:
------------
This is sortof related to a previous bug:

http://bugs.php.net/bug.php?id=33813


However, in that bug report the compile fails due to the 
PQfreemem call.  A patch was submitted to cvs that to check 
for PQfreemem, and if HAVE_PQFREEMEM = 0  use 'efree' 
instead.

As of php-5.2.1 this change seems to have been reverted, and 
systems with Postgresql < 7.4 will fail to load php-pgsql 
with the following error (or similar):

PHP Warning:  PHP Startup: Unable to load dynamic library '/
usr/lib/php/modules/pdo_pgsql.so' - /usr/lib/php/modules/
pdo_pgsql.so: undefined symbol: PQfreemem in Unknown on line 
0
PHP Warning:  PHP Startup: Unable to load dynamic library '/
usr/lib/php/modules/pgsql.so' - /usr/lib/php/modules/
pgsql.so: undefined symbol: PQfreemem in Unknown on line 0



php-5.2.0 source used 'free' rather than PQfreemem.  
Therefore, the following is a proposed patch:

http://5dollarwhitebox.org/tmp/php-5.2.1-PQfreemem.patch





Reproduce code:
---------------
Build php-5.2.1 with '--with-pgsql', install, and run a simple test with 'php -v' in order to load the pgsql.so.

Expected result:
----------------
No errors when loading pgsql.co.

Actual result:
--------------
you@linuxbox ~/]# php -v

PHP Warning:  PHP Startup: Unable to load dynamic library '/
usr/lib/php/modules/pdo_pgsql.so' - /usr/lib/php/modules/
pdo_pgsql.so: undefined symbol: PQfreemem in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library '/
usr/lib/php/modules/pgsql.so' - /usr/lib/php/modules/pgsql.so:
