Yes, but libpqrcv_get_dbname_from_conninfo() is an exposed function,
we can implement something internal for libpqwalreceiver.c like
conninfo_add_defaults() present in fe-connect.c.

more such variables as well and apart from avoiding extra round trips,
the idea to append options to provided options (if any) sounds more
logical to me.
