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.
