upgrade 8.0.4 to 8.1.4 breakage

[brian ally <brian@xxxxxxxxxxxxxxxx>]

fedora core 2, upgrade from 8.0.4 -> 8.1.4 via RPM

I've just upgraded, everything /seemed/ to go swimmingly, but now i 
cannot connect via PHP. I can connect fine through psql, and all my 
tables have been restored fine.

Using PEAR MDB2 wrappers (MDB2-2.0.3). Has anyone else seen this? Is 
this a PEAR issue?

A similar upgrade on fedora core 4 went very well. The only difference 
there was it was done from source. Any debugging advice accepted.
