Before running the commands shown on this page, you should load the Bitnami stack environment by executing the installdir/use_APPNAME script (Linux and Mac OS X) or by clicking the shortcut in the Start Menu under “Start -> Bitnami APPNAME Stack -> Application console” (Windows). Learn more.
Modify the following option in the installdir/apps/phppgadmin/conf/httpd-app.conf file to increase the allowed size for uploads:
<IfModule php5_module>
php_value upload_max_filesize 80M
php_value post_max_size 80M
</IfModule>
If you are using PHP-FPM, modify the settings in the installdir/apps/phppgadmin/conf/php-fpm/php-settings.conf file
php_value[upload_max_filesize]=80M
php_value[post_max_size]=80M
