Unable to start postgresql

I was unable to get postgres started so I did a very basic compile/install
to test it. The configuration line was:

./configure --prefix=/usr/postgres-9.6.2

--------------------------------
Then I ran make which completed as expected:

make[1]: Leaving directory '/tmp/postgresql-9.6.2/config'
All of PostgreSQL successfully made. Ready to install.

--------------------------------------
Then make check

make check

=======================
All 167 tests passed.
=======================

make[1]: Leaving directory '/tmp/postgresql-9.6.2/src/test/regress'
----------------------------------------

Then make install as user root because of directory permissions. I have
the expected files in /usr/postgres_9.6.2

Now, running as user postgres I try and start as stated in the manual

postgres -D /usr/pgsql_tablespaces

initdb has already been run and the directory pgsql_tablespaces has a
number of files as expected. As yet no database has been defined because
psql won't start.

The result is:
[postgres(at)prod04 postgresql-9.6.2]$ postgres -D /usr/pgsql_tablespaces
LOG: could not bind IPv4 socket: Cannot assign requested address
HINT: Is another postmaster already running on port 5432? If not, wait a
few seconds and retry.
LOG: database system was shut down at 2017-03-07 22:22:57 EST
LOG: MultiXact member wraparound protections are now enabled
LOG: database system is ready to accept connections
LOG: autovacuum launcher started

Same results if I use pg_ctl to start the process.

I checked with lsof and there is no process bound to socket 5432. There is
no entry in /var/run for a socket related to postgresql.

I thought it might be a security issue so I put SELinux in permissive mode
but the result is the same. The SELinux journal does not show any warnings
on this process.

[root(at)prod04 postgresql-9.6.2]# sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive <------permissive mode**
Mode from config file: permissive
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 30
-----------------------------------------------------------------

One thing that I haven't been able to find any the log files. Where are they
normally stored?

So, any ideas as to where to go next to debug this would be appreciated!
This is a brand new server that I am trying to configure so I have a fair
amount of security clearance to chase things.

Thanks in advance.
