# ******************************* WARNING *********************************
# Do not run this script until you have read and understood the information
# below, AND backed up your database. Failure to observe these instructions
# may result in losing all the data in your database.
#
# 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
#
