@0x6f736f646f ,
This PR will not solves the issue #1661 ,This PR will fix if there already datatype exisits

To replicate the issue #1661
Running Mainflux latest version with db in docker or standalone,
Then downgrade the Mainflux version to v0.12 without clearing the users service DB in docker volume or standalone Postgres database ,

The problem in the issue #1661,
If we use the same latest mainflux users docker db volume or standalone postgres database
in downgrade version like v0.12, In v0.12 there is no user_5 migrations, So migrate library throw error if there is any unknown migration in database.

Fix
To Ignore unknown migration add the line migrate.SetIgnoreUnknown(true) at https://github.com/mainflux/mainflux/blob/master/users/postgres/init.go#L91 will solve the error in issue #1661 .
