I have tried that aswell, they either gives an invalid sql, or is rejected 
by PG :(

b.assignKeyAttr("testId", None) =
libpq.OperationalError: ERROR:  null value in column "testid" violates 
not-null constraint

b.assignKeyAttr("testId", 0) = 
libpq.OperationalError: ERROR:  duplicate key violates unique constraint 
"dummytable_pkey"

b.assignKeyAttr("testId", "NULL") = 
libpq.OperationalError: ERROR:  null value in column "testid" violates 
not-null constraint

b.assignKeyAttr("testId", "") =
libpq.OperationalError: ERROR:  syntax error at or near "," at character 
62
