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

The result is:
[postgres@prod04 postgresql-9.6.2]$ postgres -D

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

To clarify: the postmaster *is* starting here.  It failed to bind to
the IPv4 port 5432, but it must have succeeded in binding to at
least one other port (IPv6 and/or a Unix socket), else it would have
stopped and you'd have not seen the last four log lines.

It might be helpful to check with lsof to see what the postmaster
process has open after you do this.

I noticed that when I deleted the postmaster.pid file as suggested by
another answer and restarted that process issued a lot more messages
before crashing  :-(   Still couldn't connect to port 5432 though.

Meant to ask before, can you show the command you are using to connect?

Yes:

[postgres@prod04 John]$ pg_ctl start -D /usr/pgsql_tablespaces

This is the command to start Postgres.

I tried psql but it won't work, as expected, because socket 5432 is not
available.

So what is the psql connection command you are using and what is the error message you are getting?
