PGSQL Phriday #002 Summary: PostgreSQL Backup and Restore

Last week for 'PGSQL Phriday': Describe how you do backups for your PostgreSQL databases.

Changes to the public schema in PostgreSQL 15 and how to handle upgrades

In September 2021, a patch for the upcoming PostgreSQL version 15 was committed which introduces a visible change for users: the 'CREATE' privilege for the 'public' schema is no longer set by default.

PostgreSQL Upgrades are hard

Together with Lætitia Avrot and Nikolay Samokhvalov I was invited to participate in a Community Panel about PostgreSQL Upgradability at Postgres Vision 2022. During this panel each of us provided examples for how easy or complicated *PostgreSQL* upgrades still are.

Restic backup

Was asked quite a few times how I do my backups with Restic.

For more than 10 years I was using “Duplicity” for backups, but in 2019 I changed to Restic. The main reason for the change was that Duplicity still can’t handle “Big Data”, as in: larger directories. In 2009 someone opened an issue on the Duplicity bugtracker, and this problem still exists as of today. For about two years I was shifting around the problem, excluding files, trying to make the sigfile smaller. But at some point I decided that it is enough and I need to change the tool.
