We migrated some tables from 8.3 postgresql to 9.4, and when I compared tables DDL between environments, I've noticed some indices are missing (majority of them are using GIN
When I am taking 8.3 ddl for it:
CREATE INDEX serp_test2
ON serp_test
USING gin
(domainids gin__int_ops);
it gives me error:
ERROR: operator class "gin__int_ops" does not exist for access method "gin"
Is it possible to retrieve the ddl for operator class and recreate it on 9.4? If not, is there any work-around?
Thank you
