# Do not run this script until you have read and understood the information

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