The first argument is the input text as a C string, the second
argument is the element type's OID in case this is an array type
(or the type's own OID for a composite type),
argument is the type's own OID (except for array types, which instead
receive their element type's OID),
and the third is the <literal>typmod</> of the destination column, if known
(-1 will be passed if not).
The input function must return a value of the data type itself.
