Avoid setup work for invalidation messages at start-of-(sub)xact.
Instead of initializing a new TransInvalidationInfo for every
transaction or subtransaction, we can just do it for those
transactions or subtransactions that actually need to queue
invalidation messages. That also avoids needing to free those
entries at the end of a transaction or subtransaction that does
not generate any invalidation messages, which is by far the
common case.
Patch by me. Review by Simon Riggs and Andres Freund.
