That doesn't sound like anyone I know of who actually works on PostgreSQL, and certainly not anyone I'd consider part of the PostgreSQL "community." The mailing lists, IRC channel and other forms of community communication are much more hostile to Oracle than any other RDBMS, and anyone who tries to start a flamewar there (particularly one about MySQL) is instantly shut down. I'm really sorry that you've been turned off from great technology by the actions of some overzealous Postgres users.
