>
> Postgres allows multiple schemas on a database user's search path, that is 
> users can query from tables in different schemas without the need of 
> prefixing the tables in the query. 
> This can lead to confusion when after an unsuccessful upgrade DBA's restore 
> the tables into a different schema (e.g. public) to Ambari's configured one. 
> As a result, Ambari server may see corrupt data.
> New consistency checks on server startup should warn the user in such 
> situations.
