Hello, For my object-relational database class I decided to use PostgreSQL because it is my favorite database and it calls it self a ORDBMS. Little did I know that it supports supports very little OR features. For example, using "create type as" is totally worthless because you can't use it as a field type in a table; you can't compose in another "create type as"; and you can't inherit another composite type. The only way to create a true type is to use "create type" and write C code as a shared object, so I'm basically doing everything C, which is not something I want to do. I've searched the mailing lists and have found little said about the OR features. Am I missing something here? Does PostgreSQL support OR features similar to Oracle 9i (which is what I'm forced to use). I really do not want to use Oracle because I have to switch over to my Windows partition, and Oracle takes about 100 MB of virtual memory on my 256 MB machine. Thanks, Yasir
