Re: How check execution plan of a function

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 ?

TIA,
