Absolutely... I guess I posted that bit to the pgsql-hackers list.
I'm pretty sure I'm going to bump things in the -devel port and am
going to talk with Palle regarding this when 7.4 comes out that way it
will, as you state, be along major version bumps.

Talked to Tom, PostgreSQL isn't stupid and does the right thing: it
bombs out before doing any work.
