I have not looked at the patch in detail, but I noticed that some
comments in the patch seem to contain non-ASCII characters.

> * * re-emitting it as ALTER TABLE … ADD CONSTRAINT ― the column-emit

I don't think that is recommended in PostgreSQL source comments, so
these should probably be replaced with plain ASCII equivalents.

For reference, I have attached the result of a quick search below.
