Upgrading from 3.0.6 to 4.0.4

[Albert Chin <rpm-list thewrittenword com>]

I created a fresh RPM installation with RPM 3.0.6:
  $ rpm30/bin/rpm --dbpath [dbpath] --initdb
  $ rpm30/bin/rpm -Uvh [first rpm v3 package]
  $ rpm30/bin/rpm -Uvh [second rpm v3 package]

Then tried to upgrade to 4.0.4:
  $ rpm40/bin/rpm --dbpath [dbpath] --rebuilddb
  $ rpm40/bin/rpm -e -vv [second rpm v3 package]

I get:
  error: cannot open Triggername index using db3 - No such file
  or directory (2)

I don't see Triggername in [dbpath]. Should I just ignore the error
above? If I start from a fresh 4.0 database, I get Triggername:
  $ rpm40/bin/rpm --dbpath [dbpath] --initdb
  $ rpm40/bin/rpm -Uvh [rpm v4 package]

This is against RPM from CVS (rpm-4_0) and on Solaris 2.6/SPARC or AIX
4.3.2.
