Your php install doesn't know about (or can't find) the postgresql extension. Default installs don't usually include postgresql support I think. run this command ldd /usr/local/apache/libexec/libphp4.so where the second parameter is the location of your php module for apache. This will list the shared object files that php needs. If you don't see a line like this libpq.so.3 => /usr/lib/libpq.so.3 (0x4001b000) then php was not compiled to include postgresql.
