Upgrade Supermarket

Do we need to upgrade Supermarket first?

Backup PostgreSQL Database

1. Stop the Supermarket application

sudo supermarket-ctl stop

1. Start the Supermarket PostgreSQL service

sudo supermarket-ctl start postgresql

1. Back up the PostgreSQL database

/opt/supermarket/embedded/bin/pg_dumpall -U supermarket -p 15432 > /tmp/supermarket-dump.sql

1. Vacuum the PostgreSQL database:

/opt/supermarket/embedded/bin/vacuumdb --all --full -p 15432

1. Reindex the PostgreSQL database:

/opt/supermarket/embedded/bin/reindexdb --all -p 15432

1. Restart the Supermarket application

supermarket-ctl restart

Recovering from Upgrade Failures

If either the vacuumdb or reindexdb commands fail

1. Drop the Supermarket PostgreSQL database

/opt/supermarket/embedded/bin/psql -U supermarket -d postgres -p 15432 -c "drop database supermarket"

1. Recreate the Supermarket PostgreSQL database

/opt/supermarket/embedded/bin/psql -U supermarket -d postgres -p 15432 -c "create database supermarket"

1. Restore Supermarket PostgreSQL database from the existing dump.sql file

/opt/supermarket/embedded/bin/psql -U supermarket -d supermarket -p 15432 -f /tmp/supermarket-dump.sql

1. Restart the Supermarket application

supermarket-ctl restart
