No, the 'options' thing is exceedingly ancient. Try something like
PGOPTIONS="-fn" psql mydb
or equivalently
PGOPTIONS="-c enable-mergejoin=false" psql mydb
The GUC-at-connect-time feature is new in the V3 protocol. Offhand I do
not think libpq exposes that to its users; it does use it internally
IIRC.
