robbak said:Postgresql is the best SQL database available at present - certainly the best Open Source one, anyway. With the current state of MySQL, i don't expect that to change any time soon. You've made the best choice.
The only reason to choose MySQL is if your application does not support postgres - and even then, you should consider changing your application, IMHO.
hark said:The only problem I've had with PostGRES on FreeBSD is that PostGRES uses SysV IPC stuff, which gets disabled by default within a jail (since enabling it gives direct access to system memory, IIRC) -- so to run PostGRES inside a jail you effectively have to open up a fairly large security hole.
From within the PostGRES jail or the host machine --trasz@ said:I seem to remember that this was fixed some time ago. Could you verify? Just compare "ipcs" output inside the jail and outside. Can you see the segments created outside (i.e. the ones belonging to the xserver) from inside the jail?
