PostgreSQL Configuration

Service management commands:

sudo service postgresql stop
sudo service postgresql start
sudo service postgresql restart

Changing verbosity & querying Postgres log:
1) First edit the config file, set a decent verbosity, save and restart postgres:

sudo vim /etc/postgresql/9.3/main/postgresql.conf

# Uncomment/Change inside:
log_min_messages = debug5
log_min_error_statement = debug5
log_min_duration_statement = -1

sudo service postgresql restart

Now you will get tons of details of every statement, error, and even background tasks like VACUUMs

tail -f /var/log/postgresql/postgresql-9.3-main.log

How to add user who executed a PG statement to log (editingĀ postgresql.conf):

log_line_prefix = '%t %u %d %a '
