TL;DR: Why and what options do we have to do audit trails in Postgres

Auditing is coming!


In a very high-level view, audit trails respond to the questions of who, what and when access to the database.

Probably it’s a duty if your business has to pass an audit or it has compliance issues.

This is very relevant in sectors such as fintech and healthcare.

Besides this, I found very relevant the use of audit trails when you have no-code/low-code platforms in your organization. In this kind of tool, users are not so much tech experts who access directly internal APIs and/or databases.

Here it’s important to have a trace of the changes that they apply.

State of the Art

In most of the DBMS, there is no audit trail options out-of-box.

Some modern DBaaS like Snowflake have a good audit trails solution from the standard edition. We can consider it a low-level system and you can build on it as your solution.

In the case of the best open-source DBMS (in my humble opinion), Postgres, we have several extensions that can do the work.

It’s important to highlight that in Postgres we can enable audit logs at a very basic level.
