There is a better way to do it. Compile postgres with -DUSE_SYSLOG, add
syslog=1 or syslog=2 into pg_options and it will output all elog messages
to the syslog facility with the pid. See trace.c for details.
But you won't be able to see the milliseconds fields because syslog
doesn't handle this information.

Thank you for your answer.
But in doc (pg-options.html) you got example:
#timestamp          #pid    #message
980127.17:52:14.173 [29271] StartTransactionCommand
980127.17:52:14.174 [29271] ProcessUtility: drop table t;
980127.17:52:14.186 [29271] SIIncNumEntries: table is 70% full

How can i get this information with milliseconds without using syslog ?               
Thank you for your answer.
