Suppose you’re given a query ‘SELECT 1 from tbl’ by a user and you want to know 
the name of the schema that tbl belongs to. What’s the easiest way to do this?

I know sqlite will use temp.tbl if it exists else main.tbl if it exists else it 
will search for the earliest attached schema with a table called tbl. Finding 
that involves the use of PRAGMA database_list and then querying each of the 
associated sqlite_master tables in turn for the existence of tbl until you get 
a match. Is there an easier way?
