[gentoo-user] switching production server from myswl to postgresql

[Tanstaafl]

Hi all,

Ok, this has been on my ToDo list for a while, and I'm thinking of 
tacking this over the holidays, since the office will be much slower 
than usual.

The only databases I have in use are for my mail server, which means 
postfix, courier-imap (soon to be dovecot 2.1 once it is released) and 
postfixadmin for maintaining the database.

First question - I can run both mysql and postgresql at the same time, 
right? I haven't found anything saying I can't, and mysql doesn't seem 
to 'block' installing postgresql, so I'm guessing I can.

Second question - has anyone ever converted an existing production mysql 
database to postgresql? If you have ever done this specifically for 
postfixadmin, I'd love to chat for a few minutes, but pointers to 
recent, accurate docs - even generically (not specifically for 
postfixadmin) for doing this would be appreciated.

Thanks,

Charles
