missing test_xxx_pre task for some adapters
a better (default) table_exists? (aligned with columns_internal) for all
[oracle ] (MATRIALIZED) VIEWS/SYNONYMS should be usable table names

[oracle] native database types ala oracle-enhanced adapter
generic JDBC XML retrieval support for all adapters
[db2] working XML column type support
[oracle] XMLTYPE column support - can't test due bug in driver
cleanup + OOP-ize extractTableName
