It was SELinux denying apache permission to make TCP connections!
I thought I had SELinux turned off but it wasn't. To be sure it is do
/usr/sbin/sestatus | grep SELinux
and if it comes back with anything other than SELinux status: disabled it's
still running.
While I was talking to the php board I discovered you can configure php to
run from the command line (mine was by default). So I wrote this bit of php
(obviously change the database name and you may need a user and passwd)...
<?php
$dbconn=pg_connect("dbname=lumbribase");
if ( ! $dbconn ) {
echo "Error connecting to the database !<br> " ;
printf("%s", pg_errormessage( $dbconn ) );
exit(); }
else {echo "connected", "\n";}
?>
....saved it as test.php and at a shell prompt ran...
[john@ tmp]$ php test.php
connected
If you get 'connected' you know php and postgres are talking via tcp and
some secondary process (firewall/SELinux) is preventing the apache
connection.
Thanks for the help.

"Permission denied" is a pretty strange error for a TCP connect failure,
as that is not a filesystem operation.
Are you able to connect with psql, or some other non-php client?
Use "psql -h localhost" to make sure it tries a TCP connection not
a Unix-socket connection.
Thanks. You mean like this? This connects without an error.
