The implementation of that feature involves injecting nodes into the raw parsetree where explicit parentheses appear. Various places in parse_expr.c that test to see "is this child node of type Foo" need to look through such nodes, else we'll get different behavior when operator_precedence_warning is on than when it is off. Note that we only need to handle this when testing untransformed child nodes, since the AEXPR_PAREN nodes will be gone anyway after transformExprRecurse. Per report from Scott Ribe and additional code-reading. Back-patch to 9.5 where this feature was added. Report: <ED37E303-1B0A-4CD8-8E1E-B9C4C2DD9A17@elevated-dev.com>
