This new identifier type provides support for 64-bit unsigned values, to be used in catalogs, like OIDs. An advantage of a new data type is that it becomes easier to grep for it in the code when assigning this type to a catalog attribute, linking it to dedicated APIs and internal structures. The following operators are added in this commit, with dedicated tests: - Casts with integer types and OID. - btree and hash operators - min/max functions. - C type with related macros and defines, named around "Oid8". This has been mentioned as useful on its own on the thread to add support for 64-bit TOAST values, so as it becomes possible to attach this data type to the TOAST code and catalog definitions. However, as this concept can apply to many more areas, it is implemented as its own independent change. This is based on a discussion with Andres Freund and Tom Lane. Bump catalog version.
