Can you test this against the 3.9 alpha? There won't be another 3.8 release short of a security release or critical bug being found, and there were a couple changes to the session table schema in 3.9 which if I had to guess based on the "character varying" part of the error message should be fixed.

(Also for future reference, either copying in the actual error message or providing a translation if it's not in English would be preferred, that way someone can easily copy/paste the message into something like Google Translate if the message isn't in their native language or core's default English)

I tested successfully (no error) with 3.9-dev branch.
Could you give the reference of the issue or the commit fixing this bug ?
Thanks a lot.

Probably #19708
