Re: logging connections

please clarify the following:

log_destination (string)
PostgreSQL supports several methods for logging server messages, including stderr and syslog. On Windows, eventlog is also supported. Set this option to a list of desired log destinations separated by commas. The default is to log to stderr only. This option can only be set at server start or in the postgresql.conf configuration file.

can u please tell what do "stderr" and "syslog" mean?

thanks,
regards

i did the above, however still no looging is being done.

for eg if i have a c++ program where i establish a connection to postgres and does some activity.

the postgres log should log the above connection to postgres when i run the program.

similarly say if i do psql database_name

this is also another connection, and shd get logged.

however by the changes u suggested, i am not able to do so.

thanks,
reagrds

You need to edit your postgresql.conf file and in the "Error reporting and
logging" section set "log_connections=true", "log_disconnections=true", and
"log_hostname=true"
