Maybe other details about the source of the problem help. The problem occured when I tried to optimize the specified function. It was running in about 3 seconds, and I needed to be faster. I make some changes and I run the well known "CREATE OR REPLACE FUNCTION ..." After that, my function execution took so much time that I had to cancel it. I restored the previous function body, but the problem persisted. I tried to drop it and create again, but no chance to restore the original performance. So I was forced to restore the database from backup.
Also I found the problem is reproductible, so a change of function will damage its performance. Can anyone explain what is happen ? How can I found the problem ?
