Doc Text:
Previously, upgrading from 3.2 to 3.3 only backed up the database after changing ownership of all objects. If failure occurred before the ownership was updated, no backup will be created, or the restoration will be performed from a different backup. Now, the backup is performed before any changes are made to the database, and all ownership changes are run in a single psql command.

Description Yedidyah Bar David 2013-12-26 14:06:32 UTC
Description of problem:

Upgrade from 3.2 does:
1. create a database user 'engine_history'
2. Update ownership of all objects to this user
3. backup
4. update the schema to 3.3

This means that if we fail during 1 or 2, we have no backup, and if we fail during 4 we restore from a backup that is different from what we started with.

We should backup as soon as possible, then start doing other things.

ok is32.2.

backup before `rhevm-dwh-setup' and one created by upgrade itself is equal.

# /bin/su -l postgres -c "PGPASSWORD=123456 /usr/bin/pg_dump -C -E UTF8 -w --disable-dollar-quoting --disable-triggers --format=p -Fc ovirt_engine_history" > ovirt_engine_history
# rhevm-dwh-setup
