It's the first time that I can't find the answer about some tech problems
Here's my problems:
>>conn=psycopg2.connect(database="mydb", user="postgres", password="123",port=5433)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
psycopg2.OperationalError: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
1.my postgreSQL is running
2.my listeningport is 5432 for sure
3.
root@lanston-laptop:~# psql -l
Password:

This is the problem that so many people asked,but there's no answers.
Thanks a lot
