Description

We replace the database name with keyspace name for all the cases expect show queries.
The current change is to replace only if keyspace name is different than database name and also only for select queries when the fields database name is set to underlying database name.

Looks good. Just curious about the purpose - is this about performance/optimization or about a logical fix, or anything else?

The earlier changes was about logical fix regarding database name in fields metadata. But, it was not doing the correct thing. So changed to fix it.
