When it comes to usermaps, they're dumped as part of FOREIGN SERVERs, so I broke out the usermap as being an independent component from the definition of the FOREIGN SERVER itself. I realize we don't currently have a way to ask pg_dump to exclude user mappings, but it seemed like it wouldn't be unreasonable for us to have that in the future as user mappings include role names and we have similar options for avoiding specific role names in a dump (eg: --no-owner). I agree that there's nothing to lock for usermaps though, as they aren't associated with tables. > Seems reasonable otherwise.

Agreed. Thanks! Stephen
