Upgraded from Fedora 15 to Fedora 17 and installed Postgres db as I needed the functionality of a server-side query. After the upgrade, I was unable to log on to phpPgAdmin and in the httpd error log I was seeing the message.
PHP Strict Standards: Only variables should be passed by reference in /usr/share/phpPgAdmin/redirect.php on line 14
Finally, I thought about SELinux and in the boolean options section there is an option
apache - Allow HTTPD scripts and modules to access databases
I enabled this option and the problem is solved.
For those who use the command line
setsebool -P httpd_can_network_connect_db 1
