8 # This script is used to upgrade StatusNet's PostgreSQL database to the
9 # latest version. It does the following:
11 # 1. Dumps the existing data to /tmp/rebuilddb_psql.sql
12 # 2. Clears out the objects (tables, etc) in the database schema
13 # 3. Reconstructs the database schema using the latest script
14 # 4. Restores the data dumped in step 1
16 # You MUST run this script as the 'postgres' user.
17 # You MUST be able to write to /tmp/rebuilddb_psql.sql
18 # You MUST specify the statusnet database user and database name on the
19 # command line, e.g. ./rebuilddb_psql.sh myuser mydbname
