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. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's On-Demand Production Tuning ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
