pg_field_type() returns a string containing the base type name of the given field_number in the given PostgreSQL result resource.

Poznámka: If the field uses a PostgreSQL domain (rather than a basic type), it is the name of the domain's underlying type that is returned, rather than the name of the domain itself.
