How to log PostgreSQL queries?

Question

How to enable logging of all SQL executed by PostgreSQL 8.3?

Edited (more info) I changed these lines :

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

And restart PostgreSQL service... but no log was created... I'm using Windows Server 2003.

Any ideas?

Answer 1

Set log_statement to all:

Error Reporting and Logging - log_statement

Answer 2

+1 to above answers. I use following config

log_line_prefix = '%t %c %u ' # time sessionid user
log_statement = 'all'

Answer 3

You also need add these lines in PostgreSQL and restart the server:

log_directory = 'pg_log'                    
log_filename = 'postgresql-dateformat.log'
log_statement = 'all'
logging_collector = on
