As soon as you get there you need an or operator to be able to say 9.0 |
9.1, or maybe some comparison operators to say >= 9.0.  Remember that
about all extensions we have are source-compatible with many different
releases of PostgreSQL.

So having the PostgreSQL server itself as an extension so that you can
require it is 9.2 material at best in my opinion.
