    Descrição

    pg_field_type(PgSql\Result$result, int$field): string

    pg_field_type() returns a string containing the base type name of the given field in the given result instance.

    Nota:

    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.

    Nota:

    This function used to be called pg_fieldtype().
