PGSQL Phriday #002 Summary: PostgreSQL Backup and Restore

Last week for “PGSQL Phriday” I posted the following task:

Describe how you do backups for your PostgreSQL databases.

And I added a bonus question: Is pg_dump a backup tool?

PGSQL Phriday #002: PostgreSQL Backup and Restore

Thanks to Ryan Booz we now have the #PGSQLPhriday blogging series. The second edition is about backups. And of course also about restore.

PGSQL Phriday #001: Two truths and a lie

Uh, what is this #PGSQLPhriday thing about? Everyone is writing blog posts about this today … For details, please read the introduction from Ryan Booz.

This month’s topic: pick your three favorite or most important best pratices for #PostgreSQL. Tell them in a form that two are true, one is a lie. See if you can spot which one is true and which one is false. The resolution is at the end of this blog posting.

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. This is a recommendation from CVE-2018-1058.

PostgreSQL Upgrades are hard

Together with Lætitia Avrot and Nikolay Samokhvalov I was invited to participate in a Community Panel (YouTube video) about PostgreSQL Upgradability at Postgres Vision 2022. The panel was moderated by Bruce Momjian and initiated and organized by Jimmy Angelakos. Bruce did talk with each of us before, which helped a lot to guide the discussion in the right direction. The recording of the panel discussion is available on the Postgres Vision website.

During this panel each of us provided examples for how easy or complicated PostgreSQL upgrades still are.
