Do you mean in general, or for the postgres_fdw specifically ?
In general, only valid column types should be accepted in the
CreateForeignTableStmt. The CreateForeignTableStmt is passed through
DefineRelation, which takes care of looking up the actual data types.
For the postgres_fdw POC implementation, this is done by parsing the
attributes type from the query result with the regtype input functions. The
attribute typmod is injected too.
