I can't see errors in log-files.
Daemon was started by gentoo init script:
start() {
checkconfig || return 1
ebegin "Starting PostgreSQL"
if [ -f "$PGDATA/postmaster.pid" ] ; then
rm -f "$PGDATA/postmaster.pid"
fi
start-stop-daemon --start \
--pidfile "${PGDATA}/postmaster.pid" \
--chuid ${PGUSER}:${PGGROUP} \
--exec /usr/bin/postmaster \
-- \
-D "${PGDATA}" \
--silent-mode=true \
${PGOPTS}
eend $?
}

My bet is that something has ipcrm'd the SysV semaphores that Postgres
uses.

Hmm. You may be right, because each apache restarting i manualy removed
used by apache semaphores..... Ok i'm try to disable this and check.
