It seemed that the majority opinion in this thread was to eliminate
the confusion by dropping the short form "d" switch in pg_dump and
pg_dumpall --- if you want that behavior you'll have to write
"--inserts".
For consistency I suggested also dropping the short form switch
"D" for "--column-inserts", although this is not absolutely necessary
in terms of eliminating a conflict.
Last chance for objections ...
