Make pg_dump's table of object-type priorities more maintainable.
Wedging a new object type into this table has historically required manually renumbering a lot of existing entries. (Although it appears that some people got lazy and re-used the priority level of an existing object type, even if it wasn't particularly related.) We can let the compiler do the counting by inventing an enum type that lists the desired priority levels in order. Now, if you want to add or remove a priority level, that's a one-liner. This patch is not purely cosmetic, because I split apart the priorities of DO_COLLATION and DO_TRANSFORM, as well as those of DO_ACCESS_METHOD and DO_OPERATOR, which look to me to have been merged out of expediency rather than because it was a good idea. Shell types continue to be sorted interchangeably with full types, and opclasses interchangeably with opfamilies.
