Thanks for updating the patch!

If we expose this function as an FDW helper function, it should return
a complete UserMapping object, including umoptions.
However, if postgres_fdw_get_connections() is the only user of this function,
I'm not inclined to expose it as an FDW helper. Instead, we can either get
the user ID by user mapping OID directly in connection.c using SearchSysCache(),
or add the user ID to ConnCacheEntry and use it in postgres_fdw_get_connections().
Thought?
