Actually, looking closer, this would also trigger on '#' used inside a
SQL literal, which seems to move the problem cases into the "pretty
likely" category instead of the "far-fetched" one.  So I'd only be OK
with it if we made the lexer smart enough to distinguish inside-a-SQL-
literal from not.  That might be a good thing anyway, since it would
allow us to not choke on literals containing '}', but it'd be a great
deal more work.  You might be able to steal code from the psql lexer
though.
