Log message:
	Implement IS OF and IS NOT OF type predicate.
	Can now do queries of the form: SELECT value IS OF (integer, float8);
	Define macros for handling typmod manipulation for date/time types.
	Should be more robust than all of that brute-force inline code.
	Rename macros for masking and typmod manipulation to put TIMESTAMP_
	or INTERVAL_ in front of the macro name, to reduce the possibility
	of name space collisions.
	Allow bit string constants without fully-specified length declaration.
	Try implementing CREATE TABLE/OF as a mapping to inheritance.
	May be appropriate, or may be replace later with something more exactly
	like one might expect from databases without the feature.
