Unfortunately we had to make a small change to the database schema for 5.1.0 version of the Tigase server.
The good news it does not affect data or data structure, only the way some data is accessed in database. We added one more stored procedure which has to be installed in database if you upgrade your installation from a previous Tigase version.
Therefore the schema upgrade is very simple and safe but make sure the current database schema is in version 4.0.
Assumptions:
- tigasedb is a database name
- tigase_user is a database user name
- admin_db_user is database admin user name
First things first - make a database backup:
pg_dump -U tigase_user -W tigasedb > tigasedb_dump.sql
If you need to restore database for any reason execute following commands:
dropdb -U admin_db_user -W tigasedb createdb -U admin_db_user -W -O tigase_user tigasedb psql -U tigase_user -W tigasedb < tigasedb_dump.sql
Now we can run schema upgrade script
psql -q -U tigase_user -W tigasedb -f database/postgresql-schema-upgrade-to-5-1.sql
