[migration-engine/connectors/sql-migration-connector/src/sql_renderer/postgres_renderer.rs:1011:22] We should only be setting a changed default if there was one on the previous schema and in the next with the same enum.

Context

This error is happening because we're attempting to unwrap a None value into default_str via an expect() call:

https://github.com/prisma/prisma-engines/blob/1efe6d372597cdb48067c5dd1f441702a1b0861e/migration-engine/connectors/sql-migration-connector/src/sql_renderer/postgres_renderer.rs#L1006-L1020

Potential Solution

I think we should conditionally apply the SET DEFAULT expression in the pushed statement only when default_str is a Some(_). I could easily do that as a side task.

I am pretty sure this is a duplicate of #15705
