+-- The following commands tweak a koji db snapshot for use with a new datacentre
+-- In addition to this script, the following actions may also need to be taken (generally afterward)
+-- * apply any needed schema upgrades
+-- * reset the koji fs volume
+--
+-- Example commands for db reset:
+-- % su - postgres
+-- % dropdb koji
+-- % createdb -O koji koji
+-- % pg_restore -c -d koji koji.dmp
+-- % psql koji koji < koji-stage-reset.sql
+--
+-- Alternate example for shorter downtime:
+-- % su - postgres
+-- restore to a different db first
+-- % createdb -O koji koji-new
+-- % pg_restore -c -d koji-new koji.dmp
+-- % psql koji-new koji < koji-stage-reset.sql
+-- [apply db updates if needed]
+-- [set kojihub ServerOffline setting]
+-- => alter database koji rename to koji_save_YYYYMMDD;
+-- => alter database koji-new rename to koji;
+-- [reset koji-test fs]
+-- [unset kojihub ServerOffline setting]
+
+
+
+-- Legacy from staging script possibly not needed
+-- wipe obsolete table that only causes problems with the sync, could
+-- even be dropped entirely (together with imageinfo table).
