pg_dump --help says:
 -d, --inserts               dump data as INSERT commands, rather than COPY -D, --column-inserts        dump data as
INSERTcommands with column names 

So one of those two commands will output insert commands instead of
copy commands.  note that insert commands tend to run a bit more
slowly, even if you enclose them in a transaction.
