Improve tab completion of IMPORT FOREIGN SCHEMA in psql 

It is not possible to get a list of foreign schemas as the server is not
known, so this provides instead a list of local schemas, which is more
useful than nothing if using a loopback server or having schema names
matching in the local and remote servers.
