   7    First cut at the Netezza Driver by Josh Eldridge joshuae74#hotmail.com
   8   Based on the previous postgres drivers.
   9   http://www.netezza.com/
  10   Major Additions/Changes:
  11      MetaDatabasesSQL, MetaTablesSQL, MetaColumnsSQL
  12      Note: You have to have admin privileges to access the system tables
  13      Removed non-working keys code (Netezza has no concept of keys)
  14      Fixed the way data types and lengths are returned in MetaColumns()
  15      as well as added the default lengths for certain types
  16      Updated public variables for Netezza
  17      Still need to remove blob functions, as Netezza doesn't support blob
