Postgres startup fail error I was running some code when my laptop shut down. Now everytime I connect to the server, I get an error message as follows:

ambangra@access1:~$ LOG:  database system shutdown was interrupted; last known up at 2014-04-03 04:27:57 SGT
LOG:  database system was not properly shut down; automatic recovery in progress

Does it mean the code is still running? I am unable to connect at all. Any help would be greatly appreciated. Thanks!
Hi managed to clear it up using:

pg_dump data -f


I am able to connect to the server now.
