Re: Change work_mem for one user

Hello Tom

Thank you very much for the quick response.

I just realized the issue is caused by the tool, DataGrid, I am using. In
DataGrid, when I close a tab, it does not actually disconnect from the
database so it does not re-login when I open a new tab.

Again. thank you for the help.
