Huh, I was all set to post an example of a useful application of it but then
apparently I'm wrong and it doesn't work:
postgres=# select * from generate_series(1,10) offset -1 limit 2;
generate_series
-----------------
1
2
(2 rows)
I'll leave it as an exercise for the reader to guess what I was expecting.
So given that that doesn't work I don't see any particular reason to accept
negative offsets or limits in 8.4 and on.
