 Major changes in this release:
 
-	Write-ahead Log (WAL) - To maintain database consistency in case
-of an operating system crash, previous releases of PostgreSQL have
-forced all data modifications to disk before each transaction commit. 
-With WAL, only one log file must be flushed to disk, greatly improving
-performance.  If you have been using -F in previous releases to disable
-disk flushes, you may want to consider discontinuing its use.

 	Outer Joins - We now support outer joins.  The UNION/NOT IN
 workaround for outer joins is no longer required.  We use the SQL92
 outer join syntax.
 
-	Function Manager - The previous C function manager did not handle NULLs properly,
-nor did it support 64-bit CPU's (Alpha).  The new function manager does.  You can continue
-using your old custom functions, but you may want to rewrite them in the future to use the
