pgsql: Remove justify_hours call from interval_mul and interval_div, and - Mailing list pgsql-committers

Log Message:
-----------
Remove justify_hours call from interval_mul and interval_div, and make
some small stylistic improvements in these functions.  Also fix several
places where TMODULO() was being used with wrong-sized quotient argument,
creating a risk of overflow --- interval2tm was actually capable of going
into an infinite loop because of this.
