Subject: pgsql: Don't call simplify_aggref with a NULL PlannerInfo

Message-ID: <E1vPUnB-0022e0-01@gemulon.postgresql.org> (raw)
Don't call simplify_aggref with a NULL PlannerInfo
42473b3b3 added prosupport infrastructure to allow simplification of
Aggrefs during constant-folding. In some cases the context->root that's
given to eval_const_expressions_mutator() can be NULL. 42473b3b3 failed
to take that into account, which could result in a crash.
To fix, add a check and only call simplify_aggref() when the PlannerInfo
is set.
