Trying to use the function check_primary_key with the examples provided
in postresql 6.3.1 I am getting the error message
"fmgr_info: function 157189: cache lookup failed"
Apart from this problem I would like to extend the function of
check_foreign_key to delete the whole row instead of only the foreign_key.
I think it's possible to write a second trigger function which will delete
the whole row if the foreign_key field is null. Or do I need to customize
the refint source?
