Re: RefDB chooses NOT to communicate with latest version of PostgreSQL

Hi Frank,

this in fact indicates that the libdbi driver somehow doesn't manage
to talk to the PostgreSQL engine properly.

This looks like a crash in libdbi. This may be caused by some
incompatibility between the driver and the engine, or it's just a
plain libdbi bug. However, I've never had any such crashes with any of
the drivers that I've used, so I still suspect the pgsql driver does
not work well with the latest PostgreSQL releases.

Is there a chance to retrieve the PostgreSQL error logs? On my system,
PostgreSQL logs errors to syslog by default, so it might be
sufficient to grep /var/log/messages for "postgres" or "postmaster".

I'll try to find some time to get 9.03 running on my development box
this weekend. I'll then run the libdbi test suite to see if the driver
is the culprit.

Markus
