It's not pgbench that is paying attention to this, it's libpq. This is at least referred to in the libpq and server documentation, eg the tenth paragraph here: http://developer.postgresql.org/pgdocs/postgres/config-setting.html It might be worth more emphasis, not sure.

Anything you'd be allowed to SET can be set from PGOPTIONS (-c or --var syntax). As for the special-purpose postgres command-line switches, I believe they are all equivalent to one or another GUC variable: http://developer.postgresql.org/pgdocs/postgres/runtime-config-short.html so the restrictions are the same as for the underlying variable. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
