Fixed a crash on OSX when run explain through shortcut in query editor, when
mouse is over an existing explain shape, and the popup, showing the explain
step information, is on

[Report from Atika Soki]
Don't set log_min_messages from the debugger connections, this was
stopping the non-superuser to debug the code.

Instead set client_min_messages to error for the listener connection, that will
avoid any unwanted messages to appear in message window from the listener. And,
shows the messages from the invoker only. Reported by Guillaume Lelarge
