My example is even better!
There is no need to infer the type as it is not needed!
PostgreSQL should be able to infer that no type is needed.

But, currently PostgreSQL accepts parameters with unknown types in statements like:
INSERT INTO t1 (col1) VALUES (?)
SELECT * FROM t1 WHERE col1 = ?where the column can be different types like VARCHAR or TIMESTAMPcol1 has a type and so the type of the unspecified variable can be inferred. Your is null example cannot have its typed inferred.David J.
