Hi, 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. --- Stas Kelvich Postgres Professional: http://www.postgrespro.com Russian Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
