Man you have worries ... aren't people who use identifiers with a
leading dot supposed to have problems? What about changing it to ..
instead? I mean, how does such a thing look like?

SELECT ".. some column .." FROM ".. the schema ..".".. a table .."
WHERE ".. the schema ..".".. a table ..".".. some column .."
IN ('.oh.', '.give.', '.me.', '.a.', '.break!');

If you like to, tighten it.
