I aggree - I'm not understanding the value of the project either if you look at the example here https://github.com/microsoft/pg_durable/blob/main/examples/i...

It's an interesting technical achievement I guess, but it's very bizarre to try and read this

    SELECT df.start(
        @> (
            ($$SELECT ... FROM demo.invoices WHERE status = 'pending'$$ |=> 'inv')
            ~> df.if_rows('inv',
                $$UPDATE ... SET status = 'processing'$$
                ~> (df.http(...) |=> 'resp')
                ~> df.if($$SELECT $r.ok$$,
                    -- classify, branch, wait for signal ...
                ),
                df.sleep(5)
            )
        ),
        'invoice-approval-pipeline'
    );
