"simple" dict with stop words in tsearch2

In tsearch2, I would like to use the "simple" dictionary along with my
own list of stopwords.

In other words, once the text is parsed into tokens, no stemming
whatsoever, but stopwords are removed.

Is there an easy way to produce that result, using the standard
"simple" dictionary?

sure, just specify dict_initoption. For example,
test=# update pg_ts_dict set dict_initoption='contrib/english.stop' where dict_name='simple';
UPDATE 1
test=# select lexize('simple', 'the');
lexize
--------
{}
(1 row)
