Hey @HarikiRito,
I tried reproducing this on my local machine and it seems to work fine. Can you share more details on the current behavior? Specifically a stack trace on the error, and if you can share an example schema it will also be helpful.

EDIT: in addition, what postgres version are you using? Also, are you trying to add a new field with a default value, or are you trying to add a default value to an existing column?

@rotemtam I believe the cause of this problem is when schema generate it doesn't have a "Default" field. And I'm using postgres:13.1 docker container
This happened if I add a new field with 0 as the default

migrate/schema.go

Here is the error message when I run the app

alter table "posts": ERROR: column "actual_point" of relation "posts" contains null values (SQLSTATE 23502)
