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
