pg_field_type — Returns the type name for the corresponding field number
pg_field_type() returns a string containing the
base type name of the given field
in the

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.

This function used to be called pg_fieldtype().
