An alternative is to avoid using reserved keywords as table/field
names.  It depends on which you think is uglier:

SELECT `timestamp` FROM `group`;
SELECT timestamp_, stamp, (etc.) from group_;
or any other number of one-off tweaks

IMO it's better to avoid using reserved keywords; it's not difficult
to do, even for cross-DB-platform development.  It eliminates the
possibility of forgetting backticks, and it's less dependent on the
database engine (PG uses double-quotes to escape literals, for
example) than common keywords.

If you ever want to see backtick-hell in MySQL, execute SHOW CREATE
VIEW for any nontrivial view.
