Обсуждение: proposal: option --application_name for psql
Hello we like to use psql in combination with bash - just like postgresql driver. Actually there is no simple possibility (from command line) to set application_name. We would to use different name than psql - for example "splunk", ... I tested PGAPPNAME, but it doesn't work. so my propose: 1) fix psql to respect PGAPPNAME 2) enhance --application_name parameter Options, ideas, comments ? Regards Pavel

And you can still set it as long as you use psql in "connection string mode", as you can with all the libpq parameters. --Magnus HaganderMe: http://www.hagander.net/Work: http://www.redpill-linpro.com/
