Thread: Partitioned tables, rules, triggers
Hi, I have two questions on the above: 1. I found in some postings recommended to use triggers instead of rules. Is this documented somewhere? 2. When using trigger, any examples on how to update the trigger dynamically when tables are added or deleted from the partitioned? Thanks, Amin

I now feel like I'll be missing out on not going to the pgsql conference this year.

Since I went to Portland for the mini-Postgres Day and OSCON just a couple of months ago I couldn't really ask my company to cover another trip to the same place so soon. But, there's always PGCon next May!
