    The driver does support SQLForeignKeys.  It does say it supports
this function
    in SQLFunctions.

    However, the current implementation is based on the SPI/trigger
stuff from the
    pg_trigger table.  If you don't have any trigger info, then
SQLForeignKeys will
    not report anything.  This is most likely the problem.
