Question 2

Is PostgreSQL 6.1 still supported?

Accepted Answer

PostgreSQL 6.1 is no longer supported — it has passed its end of life date (unknown). No further security patches will be issued. Upgrade to a supported version or obtain extended lifecycle support.

Question 3

When does PostgreSQL 6.1 reach end of life?

Accepted Answer

The end of life date for PostgreSQL 6.1 is not yet scheduled. Check the full PostgreSQL version timeline at endoflife.ai/postgresql.html for the latest information.

Question 4

What are the security risks of running PostgreSQL 6.1 after end of life?

Accepted Answer

After end of life, the vendor's standard support for PostgreSQL 6.1 ends, so newly discovered vulnerabilities may never be fixed unless a paid extended support option covers that version. Auditors ask about it too: PCI DSS requirement 12.3.4, for example, calls for a yearly review of vendor end-of-life announcements with a remediation plan approved by senior management.
