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.
