Lots of WARNING [dangling_edge] messages

I'm trying out the new pg-delta, it seems to run considerably faster and fix some few issues previously. However, whenever I do plan or diff, I get lots of WARNING [dangling_edge] messages like so:

[source] WARNING [dangling_edge] constraint:public.account.account_name_not_null: edge constraint:public.account.account_name_not_null -[depends]-> column:public.account.name references a fact not in the base

The migration itself appears to run fine. Should I be concerned?

On another note, the new pg-delta render seems to not wrap the migration in a transaction. This is not necessarily a problem, but I appreciated that the old pg-delta provided that convenience.

I would appreciate feedback if possible, thanks!
