I felt this is ok as we specify the keycount to be 1, so only the
key[0] will be used. Thoughts?
ScanKeyInit(&key[0],
Anum_pg_class_relkind,
BTEqualStrategyNumber, F_CHAREQ,
CharGetDatum(RELKIND_PARTITIONED_TABLE));
scan = table_beginscan_catalog(classRel, 1, key);

I felt this is ok, as the cleanup is handled in the caller function
"AlterPublication", thoughts?
/* Cleanup. */
heap_freetuple(tup);
table_close(rel, RowExclusiveLock);
I will post an update patch for the fixes shortly.
