Oracle, DB2, SQL Server and MySQL all provide hints. Hints are nothing unusual, they're the necessary fix with the large projects. The project in question was a porting project with a deadline. There was a ton of SQL that needed to be ported fast. Without hints, this is not possible, therefore, the Postgres pilot project was canceled. With hints, there would probably be far fewer consulting gigs for the postgres gurus, which may help explaining the religious zeal. Oracle is expensive, but not as expensive as the downtime.
