   @beliefer you are right. I run the following in PostgreSQL:
   ```
   > SELECT 'abcd' LIKE 'ab%_d';
   true
   > SELECT 'abcd' LIKE 'ab%_d' escape '%';
   false
   ```
   
   I should not merge it without checking on PostgreSQL. I am going to revert this one. 
   Any thoughts? @ulysses-you @maropu @cloud-fan
