pgsql: Stop reading uninitialized memory in heap_inplace_lock(). - Mailing list pgsql-committers

Stop reading uninitialized memory in heap_inplace_lock().

Stop computing a never-used value.  This removes the read; the read had
no functional implications.  Back-patch to v12, like commit
a07e03fd8fa7daf4d1356f7cb501ffe784ea6257.

Reported by Alexander Lakhin.
