Thread: WAL log compatibility between 9.1 and 9.3
Hi,
I'm upgrading my PostgreSQL 9.1.14 system to 9.3.5 and was wondering if WAL files are compatible between the two versions. I have WAL logs in AWS S3 and want to know if I need to separate the existing logs from the new logs after the upgrade.
Thanks for your help!

It is a good idea to separate WAL archives from before and after the upgrade. Yours, Laurenz Albe
no,they are not compatible.
