Why Aren't My PostgreSQL 8.3 Query Logs Being Created?

Troubleshooting PostgreSQL 8.3 Query Log Creation

This guide explains how to resolve issues with query logging in PostgreSQL 8.3. A common problem involves configuring logging in postgresql.conf with settings like:

<code>log_directory = 'pg_log'
log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log'
log_statement = 'all'</code>

Despite these changes, log files may not appear.

The solution requires careful verification of several settings within the data/postgresql.conf file:

• Explicit log_statement = 'all': Ensure log_statement is explicitly set to 'all' within the configuration file.

• log_destination and logging_collector: Verify that both log_destination (specifying where logs should go) and logging_collector (enabling the logging collector) are correctly enabled and configured.

• log_directory Permissions: Confirm that the log_directory specified (e.g., 'pg_log') exists within the PostgreSQL data directory and that the PostgreSQL user has write access to it.

By addressing these points, you should successfully enable query logging in your PostgreSQL 8.3 instance.
