Well, it seems to me that currently the FK needs in term of existing indexes and locks, and some other object lock needs, are all hardwired. Is it even safe to consider having the locks needed for certain commands not be hardwired? Provided I'm not all wrong here, I don't see how having something more flexible at restore time than at build time is a win. The drawback is that whenever you change a lock need in commands, you have to remember teaching pg_restore about it too. So my vote here is in favor of hardwired knowledge of pg_restore, matching target server code assumptions and needs. Regards, -- dim
