Re: [BUG] pg_dump does not properly deal with BEGIN ATOMIC function

or with -v:

pg_dump: warning: could not resolve dependency loop among these items:
pg_dump:   FUNCTION a_f  (ID 218 OID 40664)
pg_dump:   CONSTRAINT a_pkey  (ID 4131 OID 40663)
pg_dump:   POST-DATA BOUNDARY  (ID 4281)
pg_dump:   TABLE DATA a  (ID 4278 OID 40657)
pg_dump:   PRE-DATA BOUNDARY  (ID 4280)

...
BTW, now that I see a case the default printout here seems
completely ridiculous.  I think we need to do

    pg_log_warning("could not resolve dependency loop among these items:");
    for (i = 0; i < nLoop; i++)
    {
        char        buf[1024];

        describeDumpableObject(loop[i], buf, sizeof(buf));
-       pg_log_info("  %s", buf);
+       pg_log_warning("  %s", buf);
    }
