It is possible to remove all of the content from a Lion Calendar server using Postgres. To aid you in doing so, Apple has built out a couple of commands to make the process easier. This will nuke everything from the server and so is not something that should be lightly done. To do so, first stop the Calendar service in the Server application. Then let’s back up the database: pg_dump -U _postgres caldav -c -f /db_backups/caldav.sql Then run dropdb to remove the database itself: dropdb -U _postgres caldav Once the database is gone, run the calendar_bootstrap_database script (I prefer doing so verbosely): calendarserver_bootstrap_database -v Now you should be able…

Backing Up and Reindexing The Profile Manager Database in Lion Server
A common task when scaling databases is to reindex tables within the database. This process makes lookups faster and databases run butter. Reindexing becomes a pretty easy step before or after backing up the database as a general housekeeping step. To backup the database, you’ll use the pg_dump command, defining the user with -U and then the database with -d. In the case of Profile Manager, the database is device_management. Given that data is distributed across a lot of tables in the device_management database, the below script will backup the device_management database and then reindex each of the tables. If you follow previous articles to enable the Postgres user, you…

Working with Postgres from the Command Line in Lion Server
Mac OS X Server 10.7, Lion Server, comes with a few substantial back-end changes. One of these is the move from SQLite3 to PostgreSQL for many of the back-end databases, including Wiki and Podcast Producer (collab), Webmail (roundcubemail), iCal Server and Address Book Server (caldav) and as the back-end to the newest service in Lion Server, Profile Manager (device_management). As such, it’s now important to be able to use PostgreSQL the way we once used SQLite3, when trying to augment the data that these databases contains, as there currently aren’t a lot of options for editing this data (aside from manually of course). Postgres has a number of commands that…
