PostgreSQL nodes unable to start

All impacted nodes in PostgreSQL services have been restored and are now operational. As referenced in the previous update, mitigation measures for new nodes continue to be in effect.

Our engineering team has identified the root cause of this incident and is currently developing a permanent fix. The issue is specific to PostgreSQL 18; other PostgreSQL versions are not impacted.

We will continue to closely monitor system performance to ensure continued platform stability.

We identified an issue when trying to upgrade the version of postgres-anonymizer which was preventing new PostgreSQL nodes from starting up correctly. We have now mitigated this issue so all new PostgreSQL services will not encounter issues when starting up.

We are currently working on recycling the nodes in existing PostgreSQL services to apply this fix. Customers can elect to power cycle the service themselves in order to return back to baseline sooner.

If you continue to experience issues, please reach out to Aiven Support.
