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.
