Re: Non existent user error on restore

I'd suggest doing a plain text schema-only dump (pg_dump -s) and looking
through it for references to userid 100. You have presumably got some
objects in the database that are owned by a now-gone user. Fixing their
ownership would be the best long-term solution.

I think you'd actually need "createuser 100", ie, the name not the sysid
is what's being complained of above. It might be prudent to give it
sysid 100 as well, though.
