Readline's meta-# command is supposed to insert a comment marker at the start of the current line. However, the default marker is "#" which is entirely unhelpful for SQL. Set it to "-- " instead. (This setting can still be overridden in one's ~/.inputrc file, so this change won't affect people who have already taken steps to make the command useful.)
3d858af07e psql: initialize comment-begin setting to a useful value by default.
