Any active comments thread related to MySQL attracts a derailing holier-than-thou invasion telling us how dumb we are for not using PostgreSQL. PostgreSQL's advocates haven't quite reached the arrogance level of Oracle DBAs, granted, but they're a lot more active.
I basically stopped using (public) IRC somewhere around 2000. I have little idea what goes on in PostgreSQL's IRC channel(s). I expect it's toxic, but I'd expect that for any project's IRC presence. Public IRC is an inherently toxic medium.
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.
