I create a table copy, with indexes, and it worked perfecly. Then i dropped the original table and recreated it back by a copy of the newest. Same problems, lack during searches and indexes not used. I restart Postgresql 9.6.1 engine and now index is working perfectly! Maybe a cache or something other problems? I am really curious to understand why!
