After several minutes the rc.d script said:

pg_ctl: could not start server
Examine the log output.

Then I did:
killall -2 postgres
killall -3 postgres

And this remains procesess:
95527 pgsql 1 52 0 2159M 82400K pipewr 10 0:00 0.00%
postgres
95540 pgsql 1 20 0 2163M 83432K pipewr 0 0:00 0.00%
postgres

I can stop only via killall -9 :(
