Aw: Re: ('dog$house' = quote_ident('dog$house')) is surprisingly FALSE

What we deal with in our ordinary professional work is SQL texts, program source texts, within these, SQL identifier texts, and then the conventional display of the results of SQL and program execution. To emphasize the point about resulst display, try "\d s.*" in "\t off" mode. You'll see this:
 
              Table "s.silly name"
 Column |  Type   | Collation | Nullable | Default 
--------+---------+-----------+----------+---------
 n      | integer |           |          | 
 
But this SQL text:
 
drop table "s.silly name";
 
tells me that there's no such table.

And, indeed, there isn't. Perhaps there's a table s."silly name".

It is accidental if unfortunate that the <s.silly name> is quoted with ""'s in the \d output...
