See the "Data Types" chapter in the PostgreSQL documentation for the full story. http://www.postgresql.org/docs/7.4/static/datatype.html PostgreSQL allows users to create their own types, operators, and aggregates, so if the built-in capabilities aren't adequate for a particular application then users can extend the database as needed. http://www.postgresql.org/docs/7.4/static/extend.html You can see examples of extending PostgreSQL in the contrib directory of the source code. This may not be the specific information you seek, but it does show that users can extend PostgreSQL to fit their needs. -- Michael Fuhr http://www.fuhr.org/~mfuhr/
