Multiple SQLi buffers? (Emacs 20.4, sql-mode 2.5)

[Wayne S.]

I can't seem to create multiple SQLi buffers anymore.

    M-x sql-mysql
    M-x sql-rename-buffer
    M-x sql-mysql

used to create a second SQLi buffer.  Now the second sql-mysql
puts me into the first (and only) SQLi buffer, even though it's
been renamed (i.e., is no longer named "*SQL*").  Is there some
other way to do this now?  Thanks.
