Thank you very much!

In fact with the function "get_attidentity" it is not so hard. Please,
find the patch attached.
I've implement SET GENERATED ... IF NOT EXISTS. It must be placed
before other SET options but fortunately it conforms with the
standard.
Since that form always changes the sequence behind the column, I
decided to explicitly write "[NO] CACHE" in pg_dump.
As a plus now it is possible to rename the sequence behind the column
by specifying SEQUENCE NAME in SET GENERATED.
I hope it is still possible to get rid of the "ADD GENERATED" syntax.
