9.0.4 = Ingres 2006 Release 1
9.1.0 = Ingres 2006 R2
9.2.0 = Ingres 2006 R3 (currently still beta)

The number after the / is the build number. Two version strings which are
otherwise the same, the one with the higher build number will be more
recent. If you build yourself you can put anything in as the build number.

The commercial releases and open source ones can't be distinguished from the
version string, because it all comes from the same code base, it's only the
license under which it's distributed that differs. If you're on linux you
can check rpm for the license (rpm -qa | grep license | grep ingres),
otherwise you could check the LICENSE file under $II_SYSTEM/ingres/install -
though some people delete that directory .
