Member Function Documentation

consistent()

bool pg_type::consistent ( struct sqltype *  rvalue )

virtual

This function is used to model postgres-style pseudotypes.

A generic type is consistent with a more concrete type. E.G., anyarray->consistent(intarray) is true while int4array->consistent(anyarray) is false

There must not be cycles in the consistency graph, since the grammar will use fixpoint iteration to resolve type conformance situations in the direction of more concrete types

Reimplemented from sqltype.
