Обсуждение: [COMMITTERS] pgsql: Improve comments for execExpr.c'sisAssignmentIndirectionExpr().

Improve comments for execExpr.c's isAssignmentIndirectionExpr().

I got confused about why this function doesn't need to recursively
search the expression tree for a CaseTestExpr node.  After figuring
that out, add a comment to save the next person some time.
