Unable to load dynamic library '/usr/lib/php/modules/pgsql.so'

[eudor]

Hi to all!

Hi have a refent FC4+plesk8 install. I use mysql, so I don't need postgreSQL.

If I run in sheell mode the php command It response:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/pgsql.so' - libpq.so.4: cannot open shared object file: No such file or directory in Unknown on line 0

If I go to my plesk control panel, server--> Updater > Plesk 8.0.0 Components, I have all the components up to date, but not installed:
Application vault packages
ColdFusion support for Plesk
PosgreSQL server support

It's necessary to update this components if I don't use it?

The server is working ok (I think). How I can desactivate this warning.

Lot of Thanks!
