I don't know sql.el, but it looks like it uses comint. When a new sql call
is run, comint uses either the local host or the remote one, depending
on default-directory of the current buffer.

Further calls of sql-product-interactive seem to reuse the buffer, its
name is kept in the variable sql-buffer.

Maybe you could add some code via sql-set-sqli-hook. Something like
(completely untested):

;; Force sql-product-interactive to run on the local host.
(add-hook 'sql-set-sqli-hook (lambda () (setq default-directory "/")))

Best regards, Michael.
