The documentation for the variable 'sql-product-alist' incorrectly
describes the appropriate value for the :sqli-comint-func feature.
The documentation specifies:
> :sqli-comint-func      name of a function which accepts no
>                        parameters that will use the values of ...

However, the function actually needs to have two parameters: 'product'
and 'options'. See the following two examples in sql.el to confirm:
http://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/sql.el#n159
http://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/sql.el#n4337

The doc string for :sqli-comint-func (here:
http://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/progmodes/sql.el#n554)
needs to be changed to reflect this.
