This is not the same issue.
However, I had already disabled SELinux for other reasons.
The actual cause of my issue was the "new" private tmp facility in systemd
startup of httpd. This makes the PostgreSQL socket invisible to CGI scripts.
We have survived for many years without this before migrating to CentOS 7 so I
simply disabled this too and all came good.
Cheers and thanks,

I installed the 9.3 onto the Centos 7 server using the repo at
postgresql.org.
(http://yum.postgresql.org/9.3/redhat/rhel-$releasever-$basearch)
There is no /var/run/postgresql and find cannot find another socket
anywhere else.
Sounds similar to this:

I am in the process of migrating a bunch of databases and associated CGI

The database migration has been successful but I have an issue with psql
connections from CGI scripts.
I can connect to the 9.3 server locally with psql from the command
line, with
psql from other boxes on the LAN via TCP, via JDBC from programs and
servlets
but cannot connect locally via CGI.
If I run any of the CGI scripts from the command line they work but when
invoked by Apache, they fail with the usual question as to whether
anything is
listening on socket /tmp/.s.PGSQL.5432.
Some Linux variants think it improves security to run daemons like apache
in a context where what the daemon sees as /tmp has been mapped somewhere
else.
If you're running one of these platforms, the Postgres server and libpq
distributed by the vendor will have been hacked to cope, typically by
agreeing that the socket location is something like /var/run/postgresql/
rather than /tmp. I'm guessing your 9.3 installation was self-built
and hasn't been configured that way.
