Variables being modified in the PG_TRY block and read in the PG_CATCH
block should be qualified with volatile.
The variable waitEventSet is modified in the PG_TRY block (line 1085)
and read in the PG_CATCH block (line 1095).
The variable relation is modified in the PG_TRY block (line 500) and
read in the PG_CATCH block (line 515).
Besides, the variable objectAddress doesn't need the volatile qualifier.
Ref: C99 7.13.2.1[^1],
> All accessible objects have values, and all other components of the
abstract machine have state, as of the time the longjmp function was
called, except that the values of objects of automatic storage duration
that are local to the function containing the invocation of the
corresponding setjmp macro that do not have volatile-qualified type and
have been changed between the setjmp invocation and longjmp call are
indeterminate.
