Indeed, `executable-find' does not work in this case. I would propose
the following check, which keeps the test for local processes:

    (let ((program (sql-get-product-feature product :sqli-program))
          (buf-name "SQL"))

!     (unless (or (file-remote-p default-directory)
! 		(executable-find program))
        (error "Unable to locate SQL program \'%s\'" program))
      ;; Make sure buffer name is unique
      (when (sql-buffer-live-p (format "*%s*" buf-name))
--8<---------------cut here---------------end--------------->8---

Could you, please, check, whether this works for you?
