pg_upgrade

Tom asked about pg_upgrade as part of our initdb for timezone.

I have made some improvements to pg_upgrade in CVS and have successfully
migrated a regression database from a 7.2 to another 7.2 database using
it. (At least the tables show some data; very light testing.)

pg_upgrade is still disabled in CVS, it doesn't install, and there is no
manual page so it is still an unused command. I have made the commit so
people can review where I have gone and make comments.

To test it, you have to find the line that says 7.2 and remove the '#'
comment. This is for testing purposes only, so far.
