PGSQL PERFORMANCE 25 INDENTIFYING THE DATABASE IN A POSTGRES LOG FILE

PGSQL PERFORMANCE 25 INDENTIFYING THE DATABASE IN A POSTGRES LOG FILE

Subject: indentifying the database in a Postgres log file.

Date: Thu, 16 Dec 2004 10:48:06 +1100

I have written a program that parses a syslog file, reading all the postgres transactions. I would like to know if there is a way for postgres to log also the specific database the sql statement originated from.
The only options available in the postgresql.conf are:
#log_connections = false #log_duration = false #log_pid = false #log_statement = false #log_timestamp = false #log_hostname = false #log_source_port = false
Is this possible? Or is there a smart work around.

Regards,
Theo

In pre-8.0 the only way to do it is to log connections, grab the database from there, and add the pid to join all log rows back to the server row. In 8.0 we have log_line_prefix that can display all information.
