If you BuildRequire the database itself (likely you don't) then
postgres --version + some scripting seems to do what you want:
$ postgres --version | awk '{print $3}'
9.1.2
I suspect this isn't going to do what your users need. What happens
if they connect to a remote PostgreSQL database? I'm guessing they
could use either cartridge depending on the remote version, so you
probably want to build and install both of them, if that is possible.
More context could help, including knowing which package you are
trying to build and what this "cartridge" actually does.
