base-table: supported-type? symbol ¶Returns #t if symbol names a type allowed as a column
value by the implementation, and #f otherwise. At a minimum,
an implementation must support the types integer,
ordinal, symbol, string, and boolean.
base-table: supported-key-type? symbol ¶Returns #t if symbol names a type allowed as a key value
by the implementation, and #f otherwise. At a minimum, an
implementation must support the types ordinal, and

An ordinal is an exact positive integer. The other types are standard Scheme.
