I need to enable pg support on one of my CentOS servers. I know nothing about PHP but DRUPAL requires a DB backend and we have standardized on pg rather than mysql. The PHP.net page devoted to the subject of pg says that to enable pg support PHP must be built with the flag "--with-pgsql[=DIR]" and that the required support extension must be loaded via the /etc/php.ini file with the statement "extension=pgsql.so".
However, I have tried to find this file "pgsql.so" on the CentOS server before proceeding blindly and have come up empty. Can somebody here give me some detailed help on getting DRUPAL running with PsotgreSQL under CentOS; or at least point me to a site where I can find out how to obtatin the necessary and appropriate pgsql.so file? I cannot seem to find the necessary information on either php.net or postgresql.org.
