Module made with postgresql does not work

Friends, good night;
I am creating a module and need that he has connection to postgresql.
When trying to connect the following error occurred:

Fatal error: Call to undefined function pg_connect ()

The PHP postgre is not enabled, this value does not appear in phpinfo ().

The CWP is with postgre working, use the phppgadmin normally.
I believe that for the ADMIN area is not enabled pgsql php module.
How can I enable this module for ADM area properly?
Thanks.

How no one helped me, I had to research and work alone.
Here's the solution to my problem, I had to recompile the php that was used for the ADM area.

So others do not go through what I went through:
