Long term I see a few ways of dealing with this:

- Pull that idea of storing all sequences in one table off the
shelf and implement it. The new heap up-date-in-place function may come
in handy there.

- Find a way of allowing functions to be declared inline, to avoid
creating system functions continuously. I don't know if there's
precedent for this.

- Create a function called: gettable(reloid) returns record, that takes
a relation OID and returns all the records in it. If all the tables
you're dealing with have a similar structure, you can use this to
iteratoe over, sequences just being a special case.

There's probably more, but that's all I can think of right now.

Have a nice day,
