This is cool to see this patch taking shape.

+    my ($stdout, $stderr);
+    run [ 'psql', '-X', '-A', '-t', '-q', '-d', $dbname, '-f', '-' ],
'<', \$sql, '>', \$stdout, '2>', \$stderr or die;
+    chomp $stdout;
+    return $stdout;

Could it be possible to chomp and return $stderr as well here? It
seems useful to me to perform sanity checks after calling psql.
