Description of problem:
Fedora 19
PostgreSQL 9.2.4         (installed from Fedora rpm, user postgres)
PHP 5.5.4                (installed from Fedora rpm)
Chrome 30.0.1599.101
Apache Web Server 2.4.6  (installed from Fedora rpm, user apache)

I have been trying to execute the following script in my browser:

<?php
$pgsql = pg_connect("dbname=stats user=andrew");
if (!is_resource($pgsql)) {
    echo "Failed to connect to PostgreSQL";
} else {
    echo "success\n";
}
?>

When SELinux is set to 'permissive', the script outputs 'success' to my browser window.
When SELinux is set to 'enforcing', I see the following error in my browser window and in my http error_log:

Warning: pg_connect(): Unable to connect to PostgreSQL server: could not connect to server: Permission denied 
Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? 
in /var/www/html/stats_drill/connectPgres.php on line 2

followed by the output 'Failed to connect to PostgreSQL'

I get an SELinux Alert:

SELinux is preventing /usr/sbin/httpd from 'connectto' accesses on the unix_stream_socket /run/postgresql/.s.PGSQL.5432.

If you think that by default, httpd should be permitted access connectto on  .s.PGSQL.5432 unix_stream_socket.     
then report this as an error.
You can generate a local policy module to allow this access.
Do
Allow access now by executing:
# grep httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

When I try to execute 'grep httpd /var/log/audit/audit.log | audit2allow -M mypol' as root, I get the message:
compilation failed:[0D]
sh: /usr/bin/checkmodule: No such file or directory[0D]
That's all I know. :-) Thanks.

If cree que de manera predeterminada, httpd debería permitir acceso connectto sobre  .s.PGSQL.5432 unix_stream_socket.     
Then debería reportar esto como un error.
Puede generar un módulo de política local para permitir este acceso.
Do
permita el acceso momentáneamente executando:
# grep httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
