Exposed 0.56.0, postgres.
I implemented my own IdTable replica: instead of client-side .autoGenerate(), it's server-side .defaultExpression(CustomFunction("gen_random_uuid", UUIDColumnType())) (inspired from #588 (comment)).
I then generate a migration script.
Actual:
ALTER TABLE locations ALTER COLUMN id TYPE uuid, ALTER COLUMN id SET DEFAULT gen_random_uuid();
Expected:
ALTER TABLE locations ALTER COLUMN id SET DEFAULT gen_random_uuid();
