Because the Amazon Redshift documentation states the following:
"The PostgreSQL 9.x JDBC and ODBC drivers might not work correctly with all applications when accessing Amazon Redshift. Currently, Amazon Redshift recommends the following version 8.4 JDBC and ODBC drivers:"

I wouldn’t recommend it. Diagnosing problems when multiple class loaders have the same classes loaded but different versions will quickly melt your brain into a puddle of mush.
