1  Grab the source code and install the latest version of Postgres 
	--- No Brainer (Remember to check /etc/ld-elf.so.conf to make sure 
   			that the psql library is included)

2  Recover the database files from the previous version
	- In an ideal world you should have backups for old databases.  If 
	  not, reinstall the old postgres, pg_dump all the databases you 
	  care about and remember the location you parked them.
	- Start the new postgres, run
		./psql -d template1 -f DUMPFILES/OF/OLD/DATABASES
	  Now, if you go into template1 and \d, you should see tables that 
	  were in the old database
	- ./creatdb NAME/OF/NEW/DATABASE 
		- it's basically a copy of template1, so remember to drop 
		  tables that belong to other old databases before you 
		  create new databases

3  Start Postgres at bootup
	- Find a Postgres startup script and put it /usr/local/etc/rc.d
