Yes, this extension have some common functionality with patch. Particularly
yours tsvector_lexemes and mine to_array do the same thing. I wasn’t aware of
you patch when started to work on that, so I think we can ask commiter to
mention you in commit message (if it that will be commited).
And how do you use ts_match_locs_array / ts_match_locs_array? To highlight
search results? There is function called ts_headline that can mark matches with
custom start/stop strings.
