In commits 29d75b25b et al, I made pg_dumpall's dumpRoleMembership
logic treat a dangling grantor OID the same as dangling role and
member OIDs: print a warning and skip emitting the GRANT. This wasn't
terribly well thought out; instead, we should handle the case by
emitting the GRANT without the GRANTED BY clause. When the source
database is pre-v16, such cases are somewhat expected because those
versions didn't prevent dropping the grantor role; so don't even
print a warning that we did this. (This change therefore restores
pg_dumpall's pre-v16 behavior for these cases.) The case is not
expected in >= v16, so then we do print a warning, but soldiering on
with no GRANTED BY clause still seems like a reasonable strategy.
Per complaint from Robert Haas that we were now dropping GRANTs
altogether in easily-reachable scenarios.
