Wrong Typo

Hi Everybody,

I saw wrong typo in `ALTER FOREIGN TABLE´ documentation page.(
http://www.postgresql.org/docs/9.1/static/sql-alterforeigntable.html). On
the bottom of page have an example like that.
ALTER FOREIGN TABLE myschema.distributors OPTIONS (ADD opt1 'value', SET
opt2, 'value2', DROP opt3 'value3');

Don't need to put comma set options values. This is wrong usage and not
working. Need to remove comma after opt2. All of documentation series the
same(9.1,9.2,9.3,9.4...).True usage is;

ALTER FOREIGN TABLE myschema.distributors OPTIONS (ADD opt1 'value', SET
opt2 'value2', DROP opt3 'value3');

Thanks.
