Hello, I have an old application that was written on Postgres 8.1. There are a few hundreds tables, 30-40 columns per table, hundreds of views, and all the sql is inside java code. We are moving it to 8.4, it seems to be VERY slow. There are 20-30 tables transactions - the objects are spread acrross multiple tables and some tables have data from different objects. I need a short term tuning strategy minimizing rewrite & redesign. Should I start with replacing the sql with procedures? Should I start with replacing the views with the procedures to save time on recreating an execution plan and parsing? Should I start with tuning server parameters ? all your suggestions are greatly appreciated! thank you.
