Thanks Pavel  for providing updated version.
Few comments:
I felt the help text  seems incomplete:
@@ -159,6 +167,7 @@ help(const char *progname)
     printf(_("\nOptions:\n"));
     printf(_("  -e, --echo                show the commands being
sent to the server\n"));
     printf(_("  -i, --interactive         prompt before deleting anything\n"));
+    printf(_("  -f, --force               try to terminate other
connection before\n"));
     printf(_("  -V, --version             output version information,
then exit\n"));
we can change to:
printf(_("  -f, --force               try to terminate other
connection before dropping\n"));


done. maybe alternative can be "first try to terminate other connections". It is shorter. The current text has 78 chars, what should be acceptable
 
We can add one test including -e option which validates the command
generation including WITH (FORCE):
+$node->safe_psql('postgres', 'CREATE DATABASE foobar2');
+$node->issues_sql_like(
+    [ 'dropdb', '--force', 'foobar2' ],
+    qr/statement: DROP DATABASE foobar2 WITH \(FORCE\);/,
+    'SQL DROP DATABASE (FORCE) run');
+

I don't understand to this point. It is effectively same like existing test


Also should we include one test where one session is connected to db
and another session tries dropping with -f option?

I afraid so test API doesn't allow asynchronous operations. Do you have any idea, how to it?
