Hi, After issuning initdb and starting the postgres server, I checked for processes running, expecting to see just one: postgres 4926 4924 0 14:44:52 ? 0:00 /usr/postgres/8.2/bin/postgres postgres 4924 1 0 14:44:52 pts/1 0:00 /usr/postgres/8.2/bin/postgres postgres 4929 4850 0 14:44:56 pts/1 0:00 grep postgres postgres 4928 4850 0 14:44:56 pts/1 0:00 ps -ef postgres 4927 4924 0 14:44:52 ? 0:00 /usr/postgres/8.2/bin/postgres Only one of them is in postmaster.pid. What the other ones are for? more /pg_data/postmaster.pid 4924 /pg_data 5432001 31 Thanks, -----'\/\/\/`v^v^v^v^v^v^v---------------------------------------------------------------------------- Nina Markova, Database Analyst / Analyst de base de données (613) 992-3753 facsimile / télécopieur (613) 992-8836 nmarkova@xxxxxxxxxxx Geological Survey of Canada / Commission géologique du Canada Natural Resources Canada / Ressources naturelles Canada Government of Canada / Gouvernement du Canada -----'\/\/\/`v^v^v^v^v^v^v----------------------------------------------------------------------------
