I am using perl 5.005_01 with threads support and DBI/DBD::Pg.
DBI/DBD is the "standard" RDBMS-interface for perl available
from CPAN.

I have done some experimenting:
The easy parts are done (if not cleanly), connect/exec/close.
The hairy parts is to extract row descriptors and tuples
from select/fetch statements.
I am working against the current CVS tree, are there more
protocol changes in the pipeline?
