See the switches described in

https://www.postgresql.org/docs/current/static/app-postgres.html

The point of the libpq "options" argument is that you can pass server
settings using that same switch syntax, for settings you'd be allowed to
change at runtime.  This is obsolete legacy stuff; all of the available
options can be set with SET commands, and that's the preferred way to do
it now.
