Do you mean that pgsql_fdw should be a built-in extension like plpgsql so that it's available just after initdb? It would be accomplished with some more changes: * Move pgsql_fdw into core, say src/backend/foreign/libpgsql_fdw, and install dynamically loadable module during "make install" for core. The pgsql_fdw_handler function can't be included into core binary because we must avoid liking libpq with server binary directly. This method is also used for libwalreceiver of replication module. * Create pgsql_fdw extension during initdb invocation, like plpgsql. These are not trivial, but not difficult so much. However, I think contrib would be the appropriate place for pgsql_fdw because it's (relatively) special feature. -- Shigeru Hanada -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
