This is not a vote in either direction but just wanted to say that
during 7e413a0f8 where multi-row inserts were added to pg_dump, a
special case had to be added to support tables with no columns.  We
cannot do multi-inserts for that so are forced to fall back on
one-row-per-INSERT.

However, even if we had this syntax I imagine it would be unlikely
we'd change pg_dump to use it since we want to be as standard
compliant as possible when dumping INSERTs since it appears the only
genuine use-case for that is for importing the data into some other
relational database.
