PostgreSQL has a /very/ nice system of creating user-defined types,
however I am not aware of any papers directly related to design of
user-defined types for PostgreSQL. There are numerous examples
available in the contrib/ directory of all recent PostgreSQL releases.
I'd recommend reading over relevant documentation[1] to familiarize
yourself with PG's type facilities, then take a look at some of the
user-defined types in contrib/ to see some "real-world" user-defined
types.
