tty= is a dead option; it was disabled years ago on security grounds.
I'd suggest enabling query logging so you can see in the postmaster log
exactly what query string got sent by your application. The options=
string is included in the command line options for the "postgres"
backend process --- the useful part of this is
-c parametervariable=value
which is pretty nearly equivalent to doing a SET parametervariable=value
after connecting.
