Here's a completely different idea. How about we add an option that means "vacuum this table before running the test" (can be given several times); by default the set of vacuumed tables is the current pgbench_* list, but if -f is specified then the default set is cleared. So if you have a -f script and want to vacuum the default tables, you're forced to give a few --vacuum-table=foo options. But this gives the option to vacuum some other table before the test, not just the pgbench default ones.
This is a bit more complicated, and makes life more difficult to people using -f and the default pgbench tables than your proposed new -k switch. But it's more general and it might have more use cases; and people using -f with the default pgbench tables are probably rare, anyway. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
