Redundant syscache access in get_rel_sync_entry()

Hi,

in func get_rel_sync_entry() we access the same tuple in pg_class three times:

    Oid         schemaId = get_rel_namespace(relid);

    bool am_partition = get_rel_relispartition(relid);

    char relkind = get_rel_relkind(relid);

Why not just merge into one?
