PostgreSQL, Drupal CVS, table prefixes, and errors...

Ok, trying Drupal for the first time. I'm using PG 7.3.4, PHP 4.3.2. I want to have potentially several sites in one DB, so I need to use table prefixes. I was a little annoyed that there wasn't a script to do that automatically, but this did it:

$ cat addprefix
#!/usr/bin/perl

while(<>) {
s/(TABLE|INDEX|ON|INTO|SEQUENCE)\s([a-z])/$1 test_$2/g;
print $_;
}

$ ./addprefix < *pgsql | psql drupal

Does that look right?

But, at the top of every page I get:

warning: pg_exec(): Query failed: ERROR: LIMIT #,# syntax not supported.
Use separate LIMIT and OFFSET clauses.
. in /usr/local/lib/php/DB/pgsql.php on line 169.

So, is Drupal CVS simply not working with Postgres right now? What's the deal? I could fix that, but if it's not tested with PG, 10 zillion other things will probably go wrong.

So, simple question: is anyone using Drupal CVS with PG successfully?
