Connecting PHP-based Application to Postgres-9.0.3

I'm migrating our Web site to CMS Made Simple, it worked here with
postgres-8.4, but stopped working when I upgraded to postgres-9.0.0 (and I'm
now running 9.0.3). This is with php-5.2.17 on Slackware-13.1. I need help
since I don't know PHP or ADOdb.

/var/log/httpd/error_log shows:

[Tue Apr 05 16:45:39 2011] [error] [client 127.0.0.1] PHP Fatal error:
Attempt to connect to database cms on rshepard(at)localhost failed in
/var/www/htdocs/cmsms/lib/adodb.functions.php on line 85

I've attached a copy of that function.

So far the message I posted to the adodb mail list yesterday is the only
one there, and there's no response to my help request on the phplens
adodb-php Web forum.
