[0.45.1] Unable to retrieve/ add/ view users on Postgres application db

After adding a user, I always get the following error.
The application database is Postgres, not H2. This is not a known issue.

Output of user->personal-collection does not match schema: e[0;33m (not ("instance of a Collection" nil)) e[0m

Hi @t.kojima
It's generating the same errors as https://github.com/metabase/metabase/issues/13890/https://github.com/metabase/metabase/issues/10738, which would seem to indicate that there's already another user with that email or using a name that can't be handled.

Check your Postgres table core_user.
And include the full output of the table databasechangelog

Thanks for reply,

I have identified the cause of the error.

When registering a user in the browser, if using 2-byte characters (e.g. Japanese), they are percent encoded.
The column "first_name" is only allowed up to 254 bytes, but a percent-encoded string could exceed that.

Unfortunately, I am not familiar with Java and cannot directly contribute to the code fix.

How to reproduce the issue:
When registering a user, set the following for the first name.

  "Message: Batch entry 0 UPDATE \"collection\" SET \"name\" = 'ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใ‚ใฎใƒ‘ใƒผใ‚ฝใƒŠใƒซใ‚ณใƒฌใ‚ฏใ‚ทใƒงใƒณ', \"slug\" = '%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%82%E3%81%AE%E3%83%8F%E3%82%9A%E3%83%BC%E3%82%BD%E3%83%8A%E3%83%AB%E3%82%B3%E3%83%AC%E3%82%AF%E3%82%B7%E3%83%A7%E3%83%B3' WHERE \"id\" = 27 was aborted: ERROR: value too long for type character varying(254)  Call getNextException to see other errors in the batch."
