I have an idea, let me know what you all think.
rather than do:
select sum( field) from largetable
I want (need) to be able to do something like this:
select setval('myseq', select sum(field) from largetable);
and in a trigger
SELECT addval('myseq', field_size);
I have already created this function and am testing it. I basically took
"nextval" and assigned "byval" to a parameter and removed the value
caching code.
Anyway, I'm not quite getting the idea of caching sequence values. I
understand the performance benefits, but it seems problematic across
multiple backends, almost ensuring "holes" in the sequence of numbers.
