Hmmm... I think it does implicitely, with "add" and "and" in the
following:
From http://www.postgresql.org/docs/devel/static/pgbench.html:
-b scriptname[@weight] Add the specified builtin script to the list of executed scripts. [...]
Idem -f.
And later at the beginning of the Notes:
pgbench executes test scripts chosen randomly from a specified list. They include built-in scripts with -b and
user-providedcustom scripts with -f. [...]
