If you're not running that update to that first and see if it helps.

Hello Tom, Thanks for reply. You need a test case, but what it should include ? I don't know in what situations this warning is thrown. My database is quite large - hundreds of tables, tons of data... Where I should start ? Thanks ML

I doubt it's got anything to do with your data; I'd look at complex
PL functions. If you don't already know which queries trigger it,
increase your logging to find out.
