php3 does not support postgres?

[Alberto Maurizi]

        I know the subject is false: php3 DOES support Postgres.
        But in my (daily upgraded) potato it seems not to.
        A very simple call to pg_connect returns:

Fatal error: Call to unsupported or undefined function pg_connect()
in functions.php3 on line 17

        In the apache configuration the following line is present:
LoadModule php3_module /usr/lib/apache/1.3/libphp3.so
        No other references to PG or PHP modules are present.

        Does anybody have an idea of what to do to activate
        postgres functions in php3?

        Thanks,
