Here's one of the more famous articles of this type which documents the switch
from mysql to postgresql by the folks at sourcforge. (and we didnt even have

You'll note in one test postgresql performs at 6x mysql... and this was with
version 7.1.
Another interesting note is the mention that interbase was looked at and then
passed over due, in part, to "serious community and corporate issues around
it's Open Sourceness".
