RDBMS output does not work for Postgreql

[karenhanson]

If you configure the loader to use a Postgresql JDBC driver and connection, it fails on the init() method due to the incompatibility of "show tables;" The code should either be made compatible with Postgresql or the tables should be created outside of the Java code. The problem code is in this class:

https://github.com/rmap-project/rmap-loader/blob/master/rmap-loader-run-registry/src/main/java/info/rmapproject/loader/RdbmsHarvestRunRegistry.java

The exception is:
