Also, the schema in the dbmail sources makes heavy use of the INT8 data
type.  PG handles those much better on an -m64 compile than on a -m32
compile.  The speed increase I got when I converted my personal mail
store to use INT4 everywhere INT8 is currently specified -- except for
the dbmail_users table; my curmail_size is greater than 2 Gigs -- was
significant.  And I cut my disk space usage by about half.


I second that!
