BUG #14186: Inconsistent code modification

The following bug has been logged on the website:

Bug reference: 14186
Logged by: Petru-Florin Mihancea

PostgreSQL version: 9.4.4
Operating system: Macosx
Description:

File: postgresql-9.4.4/src/backend/catalog/aclchk.c
Function: pg_type_aclmask (line 4200)

At lines 4236, I think elttype_oid should be used and not type_oid. The code
is bellow:

tuple = SearchSysCache1(TYPEOID, ObjectIdGetDatum(elttype_oid));
if (!HeapTupleIsValid(tuple))
ereport(ERROR,
(errmsg("type with OID %u does not
exist",
type_oid))); <<<
POTENTIAL PROBLEM

It is searched for elttype_oid and thus elttype_oid should probably be
reported that is not found. Before this fragment, a similar search is done
for type_oid and type_oid is reported as not found (lines 4218-4222 but not
copied here). Flowing the same idea, elttype_oid should be used in the
presented case. I found this issue using a CodeSonar plugin I develop.
