[ADMIN] PostgreSQL Schema Standards Tool

Hello, Is anyone aware of tools which can be used to enforce schema standards on PostgreSQL 9.0? For examples: 1) Fail/rollback DDL attempting to create a table in the public schema 2) Create a scheduled process which raises alerts for columns of datatype XML Thanks, Robert
