Perhaps you should then first migrate from pgsql to mysql, before moving
from 1.2 to 2.0:
I once used:
pg_dump --file=/var/tmp/dbmail-dump.pgdata --format=p --data-only
--inserts --no-owner --no-reconnect --no-privileges dbmail
mysql -f dbmail < /var/tmp/dbmail-dump.pgdata
which is very slow, but should work in most circumstances (exotic
charsets are always a pain).
Also, I'm working on a sql-only solution to be included in the debian
packages. I don't want to make the dbmail packages depend on python,
python-mysql, and python-pgsql just to convert if I can avoid it. Also,
I want the conversion to be non-interactive, and in-place, that is
without resorting to different databases for dbmail1 and dbmail2.

Hey Ilja,
Sounds good, sounds likes it comming this week, its that correct
understood?? If will there be a announce of that cause its really
urgent, I
need to upgrade my system and I can't do that until I have moved the
mails
to the mysql database....
If its that migration script there is in the source right now, it does
also
fail on my system, so I sure hope you are talking about a new and
better one

These single quotes should not be necessary for Python DB.
I'll have another (better ;) ) look at migration scripts this week.

I have now tried to get the newest version that includes the

I'm trying to migrate from PostGreSQL to MySQL version 3.23.57.
If there are more information need just ask.....
I want to get the database moved ASAP.

What are the exact aliases that make the script barf?
Try: cursor_2.execute("""INSERT INTO auto_notifications
(auto_notify_idnr, user_idnr,
notify_address)
VALUES ('%s', '%s', '%s')""", record)
instead around line 113. Notice the single quotes around
the values.
Sorry for not making this a proper diff. The missing
quotes are a
generic problem I notice in this code. I'm guessing there may be
some weird chars in your aliases that drive python's string
interpolation into recursive mania.
Also, aside from messages and messageblks you should be
able to dump
and load the 1.2 tables straight into the 2.0 db.
