I have committed just the libpq change. The documentation change was
redundant, because the documentation already stated that all libpq
options are accepted. (Arguably, the documentation was wrong before.)
Also, the proposed test change didn't seem to add much. It just checked
that the foreign server option is accepted, but not whether it does
anything. If you want to develop a more substantive test, we could
consider it, but I feel that since this all just goes to libpq, we don't
need to test it further.
