Got it! Thanks, Chris!
I still wonder why application_name appears in the configuration file if it
cannot take effort :-P
Not sure what you mean by that, but my postgresql.conf doesn't have
anything about application_name. But if it did, it would be a default
that an application can override.
Actually it does:
log_line_prefix = # %a = application name
# %u = user name
# %d = database name
http://www.postgresql.org/docs/9.2/interactive/runtime-config-logging.html#GUC-APPLICATION-NAME
....
It is a chicken and egg situation. See section 31.1.2. Parameter Key
Words of below:
http://www.postgresql.org/docs/9.2/interactive/libpq-connect.html
"application_name
Specifies a value for the application_name configuration parameter."
