tweak your postgresql.conf

Markus Bertheau

Thanks for the reply Markus.  I have added

log_connections = yes
log_timestamp = true
log_pid = true
syslog = 2

to my postgresql.conf file but it dosent seem to have caused any logging to occur in

/var/log/postgresql

Anything else I need to do?

I just added

debug_print_query

restarted postgres and then did a few queries in the database.  But nothing
is being logged in /var/log/postgresql.  Any ideas what else might be wrong?

hmm, that is my postgresql.conf:

tcpip_socket = true
port = 5432
hostname_lookup = false
sort_mem = 128
shared_buffers = 12288 # min 16
fsync = off
deadlock_timeout = 10000
wal_buffers = 64 # min 4
wal_files = 4 # range 0-64
log_connections = true
log_timestamp = true
log_pid = true
debug_print_query = true
debug_print_rewritten = false
show_executor_stats = false
show_query_stats = false

what is different?

btw: I presume we talk about 7.1.x

If you're not seeing any log output at all, then either:

1. Postgres is logging to postmaster's stderr but you've directed same
to /dev/null (or not where you are looking, anyway).

2. Postgres is logging to syslog, but you've configured syslog to
discard the output (or put it somewhere else than where you are
looking).
