What happens when somebody copies their postgresql.conf from an older
version? That's hardly uncommon, even though it might be considered bad
practice. I don't think it's a good idea to try to insert a version
identifier this way.

But ... what's the point of including the PG version in this string
anyhow? If you're trying to make the string unique across different
installations on the same machine, it's surely insufficient, and if
that's not the point then what is?
