Tom,
thanks for the reply.
DBD::Pg dos indeed use PQconnectdb(),
but at least in my light test I get SEGV in $sth->fetch.
The problems are probably somewhere in DBDI or DBD::Pg or
somewhere in the interaction of the parts.

I am looking into how much work a "pure Perl" interface
should amount to. Using native perl IO and pgsql-fe/be-protocol
should make "pgsql-clienting" even more portable over platforms.
