You could get started by looking at the documentation on custom SQL types with https://www.postgresql.org/docs/current/sql-createtype.html, or look at the comments in pg_type.dat and the comments on TypInfo in bootstrap.c on how the built-in types are created and managed. Lastly, you could look at pg_class and the genbki documentation if you want to add new catalog types. Kind regards, Matthias van de Meent Neon (https://neon.tech)
