Hello Sir, I hope that you are well.

I recently upgraded from iRedMail 1.6.8 to 1.7.1 and from OpenBSD 7.3 to 7.4.

However, when attempting to upgrade to OpenBSD 7.5, the upgrade from PGSQL 15 to 16 failed with the following error:

"There seems to be a postmaster servicing the new cluster. Please shutdown that postmaster and try again. Failure, exiting"

I was not able to resolve the error, and reverted to a OpenBSD 7.4 backup with PGSQL 15 and iRedMail 1.7.1.

I am about to try again to upgrade to OpenBSD 7.5 and PGSQL 16.

Is this a good guide to follow? <https://dev.to/nabbisen/postgresql-on-o … grade-4484>

Do I have to make any iRedMail specific changes before or after? Do I have to shut down iRedMail services after upgrading to OpenBSD 7.5 and before upgrading to PGSQL 16?

Thank you for your wonderful software and support. I'm sure this will also help to migrate to PGSQL 17 in the future when it is ported to OpenBSD.
