pgstatspack - pgstatspack: Fixed a problem with the report where a table

Log Message:
-----------
Fixed a problem with the report where a table with the same name exists
in 2 seperate schemas within the same database. I also changed the way
the math was done for the table to index read ratio so it is no longer
a number in reference to the total tuples read for all tables and indexes.
