I don't particularly care for hard-wiring knowledge that bad service
name is the only other reason for PQconndefaults to fail (even assuming
that that's true, a point not in evidence ATM). I care even less for
continuing to use ERRCODE_FDW_OUT_OF_MEMORY for errors clearly outside
its meaning.
I think we should either change PQconndefaults to *not* fail in this
circumstance, or find a way to return an error message.
