phpPgAdmin exporting empty SQL dump?

you need to modify your dbexport.php in /usr/share/phppgadmin (on Ubuntu)

modify line from passthru($cmd); to echo passthru($cmd); modify line $cmd = $exe . " -i"; to $cmd = $exe;

it will be enough. Cause parameter -i seems to be deprecated in postgres 9.5 , he gave error for me.
