The proposed file_fdw.sql actually creates a default FDW on installation.
So I think the installation scripts work as a template even if we don't
have FDW template catalogs.

+ /* contrib/file_fdw/ */
+ -- create wrapper with validator and handler
+ CREATE OR REPLACE FUNCTION file_fdw_validator (text[], oid)
+ CREATE OR REPLACE FUNCTION file_fdw_handler ()
+ VALIDATOR file_fdw_validator HANDLER file_fdw_handler;
