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,
Stephen
