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().

Though the DataBaseMetaData method getPrimaryKeys() executes splendidly, I am getting errors when using the getImportedKeys() method. The code below attempts to determine whether or not a particular column is a foreign key.
