Qlik Replicate PostgreSQL 18 support - roadmap

[al3x]

Hi Qlik Support & Community,

PostgreSQL 18 was officially released on September 25, 2025, and we are planning our upgrade roadmap accordingly.

Looking at the current Qlik Replicate Support Matrix (November 2025), PostgreSQL 18 is not yet listed as a supported source or target endpoint. The latest supported versions are 14.x, 15.x, 16.x, and 17.x.

Could you please clarify:
1. Is PostgreSQL 18 support currently on the roadmap for Qlik Replicate?
2. If so, is there a target release planned (e.g., May 2026)?
3. Are there any known compatibility issues or limitations with PostgreSQL 18 that we should be aware of in the meantime?

For context, we noticed that PostgreSQL 17 support was added in the May 2025 release, roughly eight months after its initial release. We are hoping for a similar turnaround for version 18.

Thank you in advance for your response!

Kind regards
Alex

Hello Alex, @al3x 

1. I could not find any information about support for PostgreSQL 18 in the latest roadmap. I will verify this further and get back to you.
2. Same as point (1) above.
3. Based on my experience, I did not get specific issues regarding PostgreSQL 18 yet. If PostgreSQL is configured as the source endpoint, you may encounter the following warning:

[SOURCE_CAPTURE ]W: Supported major version numbers range is [9..17]. Source database version number is not supported.

Please wait until Qlik Replicate officially certifies PostgreSQL 18 as a supported source endpoint.

Regards,

John.
