If there are some tables that are extraordinarily large that would not
be good candidates, this could be excessively expensive.

If you can identify a specific set of tables that are good candidates,
then a faster option might involve:
  pg_dump --data-only --table=this_table --table=that_table
--table=other_table databaseURI

or, if there are only a few tables to omit...
  pg_dump --data-only --exclude-table=this_irrelevant_big_table
--exclude-table=another_big_irrelevant_table databaseURI
