Ummm ... pg_constraint.conname contains a constraint name, not a table
name, so casting it to regclass is highly likely to fail.  This hasn't
got anything to do with search_path AFAICS, it's just a thinko.

Depending on what it is that you're hoping to do, any of conrelid,
confrelid, or conindid might be what you're after.  All of those columns
would contain pg_class OIDs that could usefully be cast to regclass.
