[HACKERS] DROP VIEW code question

[Mark Hollomon]

In tcop/ulitity.c we have the following code fragment:

case VIEW:
{
        char       *viewName = stmt->name;
        char       *ruleName;

        ruleName = MakeRetrieveViewRuleName(viewName);
        relationName = RewriteGetRuleEventRel(ruleName);

This looks like an expensive no-op to me.
if viewname == "myview"
then ruleName == "_RETmyview" (+/- multibyte aware truncation)
then relationName == "myview"

Is this code doing something that I'm missing?

Also

"DROP TABLE x, y, z" is allowed, but

"DROP VIEW x, y, z" is not.

Any reason other than historical?
