PostgreSQL operator class incompatible with data type

PostgreSQL.*ERROR:.*operator class.*does not accept data type

Fixes

1.Use correct operator class for the data type (btree vs gin vs gist)
2.Cast the column to a supported type before indexing
3.Install btree_gin or btree_gist extension for additional type support
