DSN (write): NOT OK (could not find driver)

[unplanned]

New Roundcube install.

CentOS/Postfix/Dovecot/Roundcube/pgsql


Check config files
main.inc.php:  OK
db.inc.php:  OK
Check if directories are writable

Roundcube may need to write/save files into these directories
temp/:  OK
/var/log/roundcube:  OK

Check DB config
DSN (write):  NOT OK(could not find driver)

Make sure that the configured database exists and that the user has write privileges
DSN: pgsql://roundcube:passsword@localhost/roundcubemail

I am able to connect to database roundcubemail as roundcube with the password I have specified. It is the owner of database roundcubemail.  What am i missing?

Thanks,
A

RoundCube use the PHP PDO extension so you'll need the pdo-pgsql package.
