So your proposing we do something like the attached patch? Where we
change conninfo_add_defaults to ignore an invalid PGSERVICE if being
called by PQconndefaults() but keep the existing behaviour in other
contexts where it is actually being used to establish a connection?
In this case even if someone takes the result of PQconndefaults and uses
that to build connection options for a new connection it should fail
when it does the pgservice lookup when establishing the connection.
That sounds reasonable to me.
