Hi,
I'm running performance tests against a PostgreSQL database (9.4) with various hardware configurations and a couple different benchmarks (TPC-C & TPC-H).
I'm currently using pg_dump and pg_restore to refresh my dataset between runs but this process seems slower than it could be.
Is it possible to do a tar/untar of the entire /var/lib/pgsql tree as a backup & restore method?
If not, is there another way to restore a dataset more quickly? The database is dedicated to the test dataset so trashing & rebuilding the entire application/OS/anything is no issue for me-there's no data for me to lose.
Thanks!
