Actually, I understand that it's the DROP that's failing. What I didn't
understand is that connection closure was asynchronous, but everything else
is synchronous.

So, why can't the server-side code that closes the connection release any
resources associated with that connection before the socket is closed? It
seems that doing so could fix this problem quite cleanly.

Perhaps I'm misunderstanding the manual - "4.1: When a new database is
created, the template database [template1] is essentially cloned. This means
that any changes you make in template1 are propagated to all subsequently
created databases."

Thanks again for your quick response,
