    Description

       

      create index ix2 on default(c1) WHERE type LIKE "airport%";
      		 
      \set -$type "airport%";
      		 
      EXPLAIN SELECT 1 FROM default WHERE c1 = 10 AND type LIKE $type;

       

       

      Above adhoc query does n't choose the index. 

      Following works.

       

      EXPLAIN SELECT 1 FROM default WHERE c1 = 10 AND type LIKE "airport%";

       

       DNF transformation might not happened LIKE before index selection.
