On trying to install postgres on Ubuntu 14 I am seeing postgres is shutting down. I am seeing the below errors in logs
 LOG: listening on IPv4 address "127.0.0.1", port 5432  LOG: listening on Unix socket "/var/run/postgresql/.s.PGSQL.5432"  LOG: database system was shut down at 2017-12-16 02:41:39 PST  LOG: database system is ready to accept connections  [unknown]@[unknown] LOG: incomplete startup packet  LOG: received fast shutdown request  LOG: aborting any active transactions  LOG: worker process: logical replication launcher (PID 19050) exited with exit code 1  LOG: shutting down  LOG: database system is shut down
Can some one let me know what could be going wrong? Why is postgres shutting down after the installation ?
