hi! I've been having some serious performance issues with postgresql8.2/hibernate/jdbc due to postgres reusing bad cached query plans. It doesn't look at the parameter values and therefore does not use any partial indexes.
After trying to set prepareThreshold=0 in the connection string which didnt work, even modifying the jdbc driver and forcing it to 0 and not working I realized that it must be being ignored. After giving up pretty much I tried a much older driver which doesn't use server prepared statements at all the problem has gone away and it is once again using the partial indexes. How can I get this to work properly on the new jdbc driver? I don't really like having to use a 2 year old driver to get good performance as you can imagine :) Could someone point me to a jdbc src file where I could just disable server-side prepared statements entirely? -- thanks, G ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
