This simple makes no sense for PG release versioning schema/policy, see [1]=
.
Following schema X.Y.Z of a PG release, you may "certifies" an application
to work on version X.Y only, the Z number means the release (bug-fix/patch
basically), and you should **always** be using the most higher Z for your
X.Y version (in the case of 9.2, you should be using 9.2.8 already, no
excuses). In summary, you can always upgrade from Z to Z+1 without
compatibility issues. Of course, read the release notes to check if there
is some maintenance needed after the upgrade.
