Description:

COMMENT ON TEXT SEARCH DICTIONARY simple IS 'simple dictionary: just lower
case and check for stopword';

The following command should return {}:

SELECT ts_lexize('simple','The');

Instead it returns {the}

No, that's correct, because that dictionary instance hasn't been
configured with any stopword file.  You need to define a dictionary
that's been connected to the stopword file you want, as in the example in
