Re: JDBC Driver -- getImportedKeys

This is not a stack trace from a 7.3 or 7.3.1 driver.  The
org.postgresql.jdbc2.DatabaseMetaData class was removed between the 7.2
and 7.3 series.  Even then I can't find reference to an importLoop method
in older drivers (7.1.3 or 7.2.3).

Please check your driver, classpath settings, or
DatabaseMetaData.getDriverVersion().
