- * These data types are supported on all 64-bit architectures, and may
- * be supported through libraries on some 32-bit machines. If your machine
- * is not currently supported, then please try to make it so, then post
- * patches to the postgresql.org hackers mailing list.
- *
- * This code was written for and originally appeared in the contrib
- * directory as a user-defined type.
