[root(2)@ironclad httpd]# rpm -q php
php-3.0.12-4

The line is commented out, so it isn't a big deal, but the
line:

;extension=pgqsl.so

:should be:

;extension=pgsql.so

:to avoid possible configuration problems (it took me a
while to figure out why my postgre php stuff wasn't working
even though I uncommented out the pgsql.so line).
