Some time ago, the tab completion code for the SET command was changed to read the list of available settings from the pg_settings table. This means that by the time you're done completing SET TRANSACTION ISOLATION, you've already sent a query and the command will be disallowed. It's not a major issue, but I figured I'd mention it since it confused me a while ago. If someone has an ingenious plan for working around this, let me know.
