3 postgres processes

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,
