Hello,all.

I have installed the postgresql .

$/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data start

LOG:database system was shut down at 2011-11-10 15:36:14 CST

LOG:database system is ready to accept connections

LOG:autovacuum launcher started

 when I check the status of cluster

$/usr/local/pgsql/bin/pg_ctl -D /usr/local/pgsql/data status

pg_ctl:server is running(PID 18432)

but why I cannot create a database successfully?

 $/usr/local/pgsql/bin/createdb mydb

createdb:could nto connect to database postgres: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"?

and I did not find the ".s.PGSQL.5432" file in the whole file system.what's the wrong?

Thanks.
