The
addEquivalency
method wasn't properly handling the case when oneof the columns is constant. This causes the other column to become
constant, and thus it needs to be removed from all weak keys.
Adding a test designed to catch the general class of bugs where a
mutation causes the invariants to be invalidated; verified that it
catches the problem.
Fixes #24500.
Release note (bug fix): Fixed a crash caused by a WHERE condition that
requires a column to equal a specific value and at the same time equal
another column.
