Subject: Add support for FreeBSD
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=d4611000dbc8a44ec7b051d6d4dd47d2c37485c3;p=pgperffarm.git

Add support for FreeBSD

The memory calculations for pgbench will need to be platform specific.
Also the system data collection may have to be platform specific.  Thus
far, just added conditions so that things will run on FreeBSD now.
