Yeah, that's clearly a bug --- fix committed, thanks for the patch!

It could explain Devrim's report if the parameters passed by psql had
some problem that was detectable by conninfo_array_parse().  That seems
a bit unlikely, but I did think of one possibility: if Devrim was
testing 9.1 psql with a 9.0 libpq (perhaps due to an rpath issue)
then 9.0 libpq would spit up on client_encoding, which wasn't a legal
connection parameter in 9.0.
