Hmm, good point.  There isn't any real easy way to refer to a sequence
by OID --- the sequence functions only accept names --- but I suppose
someone out there might be doing something with sequence OIDs.

Perhaps the real answer is to extend the set of sequence functions so
that it's possible to set/clear is_called directly.  Perhaps a variant
setval() with an additional, boolean argument?
