Re: Undefined function pg_connect()

; Directory in which the loadable extensions (modules) reside.
; http://www.php.net/manual/en/ini.core.php#ini.extension-dir
; extension_dir = "./"
;extension_dir = "./;/usr/lib/php/modules/;/usr/lib/pgsql/"

These should be colon separated, not semicolon - notice it's trying to load both paths included:

PHP Warning:  PHP Startup: Unable to load dynamic library './;/usr/lib/php/modules/;/usr/lib/pgsql/curl.so'

Change it to

extension_dir = "./:/usr/lib/php/modules/:/usr/lib/pgsql/"

Then, a new message was displayed:

"Warning: pg_connect(): Unable to connect to PostgreSQL server: could not connect to server: Permission denied Is the server running on host "localhost" and accepting TCP/IP connections on port 5432? could not connect to server: Permission denied Is the server running on host "localhost" and accepting TCP/IP connections on port 5432?"

"Permission denied" sounds like either file permissions or seLinux is stopping the connection.

If you have seLinux enabled, try disabling it (don't know how to do that, sorry) - at least that will tell you if that's the problem.

For file permissions, check your apache user can read where-ever the postgres socket file is put (normally /tmp/.s.PGSQL.5432 on centos/rhel).
