I started out with the intention to rename value_type to item_type to avoid a collision with a typedef name that appears on some platforms. Along the way, I noticed that the adjacent field "format" was not being correctly handled by the backend/nodes/ infrastructure functions: copyfuncs.c erroneously treated it as a scalar, while equalfuncs, outfuncs, and readfuncs omitted handling it at all. This looks like it might be cosmetic at the moment because the field is always NULL after parse analysis; but that's likely a bug in itself, and the code's certainly not very future-proof. Let's fix it while we can still do so without forcing an initdb on beta testers. Further study found a few other inconsistencies in the backend/nodes/ infrastructure for the recently-added JSON node types, so fix those too. catversion bumped because of potential change in stored rules.
