In the buildfarm? Yes, I think so. The philosophy of the buildfarm is
that it should do what you would do yourself by hand.
And adding DBI as a requirement for running a buildfarm member would be
a significant extra barrier to entry, ISTM. (I am very fond of DBI, and
use it frequently, BTW)
I'm persuadable on most things, but this one would take a bit of doing.
A parallel psql seems to me a better way to go. We talked about that a
while ago, but I don't recall what happened to it.
