I just compiled REL8_1_STABLE branch and I still has the following behaviour: lbo=# ANALYZE cms_items; ANALYZE lbo=# explain analyze select * from cms_items where ancestors LIKE '1062/%'; QUERY PLAN ------------------------------------------------------------------------------------------------------------ Seq Scan on cms_items (cost=0.00..688.26 rows=1 width=103) (actual time=0.009..22.258 rows=11326 loops=1) Filter: ((ancestors)::text ~~ '1062/%'::text) Total runtime: 29.835 ms (3 rows) lbo=# show lc_collate; lc_collate ------------- fr_FR.UTF-8 (1 row) Do you see any reason why your patch doesn't change anything in this case? Thanks. -- Guillaume ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
