What is the version of your Kernel? I'm running PSQL on a 2.2.16-Kernel
without problems. When I updated to 2.4.0 I got problems.

Postgres don't start, though I built it from the source. The error message
is
"IpcSemaphoreCreate: semget(key=1, num=17, 03600) failed: Function not
implemented"

The same message comes when I try to start new compiled Apache.

But if you don't have 2.4-Kernel
try this:

PSQLPREFIX=/usr/local/pgsql
rm -rf $PSQLPREFIX/data
mkdir $PSQLPREFIX/data
chown postgres.daemon $PSQLPREFIX/data
su - postgres -c "$PSQLPREFIX/bin/initdb -D $PSQLPREFIX/data"
