Yeah, I think that would be the most desirable behavior.

It looks to me like the simplest way to make this happen would require
(a) adding a field to CreateSeqStmt to carry the userID we want the
sequence to be owned by;
(b) adding a parameter to DefineRelation to pass in said userID.

(Or we could add a field to CreateStmt rather than a separate parameter
to DefineRelation, but I'm unconvinced that's better.)

We could in theory back-patch this, since CreateSeqStmt won't ever go to
disk in stored rules.  However, tweaking DefineRelation's API in stable
branches seems fairly hazardous to third-party code.  Does it seem
sufficient to fix the problem in 9.0 and up?
