Comment:

 I concur. Note that the change makes the names shorter than necessary --
 the idea behind using `self.max_name_length() - 3` is to save space for
 the `_SQ` suffix, but the change now includes that suffix in the truncated
 text.

 I also think we should similarly revert the analogous change in trigger
 name truncation. I'm not sure we ever use calculated trigger names after
 the trigger is created, however,
 * if we do, then the same considerations as with sequences apply
 * if we don't, then it's better to have consistent code and use the full
 available name length
