Hi,
Is there any way to improve performance of LIKE clause on VIEWS.

select * From request_vw where upper(status) like '%CAPTURED%' - 28 seconds.

select * from  request_vw where status='CAPTURED'

Application team is reluctant to change queries from the Application side to = instead of LIKE.

Also as this is VIEW TRIGRAM nor normal indexes don't get used.


Regards,
Aditya.

You could try using the `text_pattern_ops` operator class on your index on the `status` column:  https://www.postgresql.org/docs/current/indexes-opclass.html
