Why Isn't My PostgreSQL 8.3 Logging All SQL Queries?

Debugging PostgreSQL Query Logging in Version 8.3

This guide addresses a common problem: PostgreSQL 8.3 failing to log all SQL queries despite seemingly correct configuration. A user reported that even after setting log_directory, log_filename, and log_statement = 'all' in postgresql.conf, no log files were generated.

Resolving the Logging Issue

The problem wasn't solely with the settings mentioned above. The solution requires checking these crucial additional parameters:

• log_destination: This setting must be enabled to activate logging functionality.
• logging_collector: This parameter needs to be switched on to effectively collect and store log messages.
• log_directory: Verify that the designated directory exists within the PostgreSQL data directory and that the PostgreSQL user possesses the necessary write permissions.

By carefully reviewing and correcting these parameters, you should successfully enable comprehensive SQL query logging in your PostgreSQL 8.3 instance.
