db version?

[Douglas Allen]

I have a quick question.  How do you find out what version of db is 
installed on the system, if any?  I've tried several things and I haven't 
found what I want, without having to do a small database program to pull 
the data out. I'm hoping that there is a quick way from the command line to 
get the information.  I need to now for Postfix, DRAC and a couple of other 
applications that all rely on things being compiled with the same versions.

Thanks in advance.
