使用psql出错!急,请高手指教

abchgd

刚装了Postg8.0.1,安装成功没有报错,数据库也起来了可使用psql出错!如下:
$pg_ctl start
LOG:database system was shut down at 2005-02-05 10:59:02 CST
LOG:checkpoint record is at 0/A2CA38
LOG:redo record is at 0/A2CA38;undo record is at 0/0;shutdown TRUE
LOG:next transaction ID:544;next OID:17230
LOG:database system is ready
$psql
LOG:setsockopt(TCP_NODELAY) failedrotocol not available
psql:server closed the connection unexpectedly
         This probably means the server terminated abnormally
         before or while processing the request.
