Hi all,<br /> I just want to ask you if it's possible to define sub types in PostgreSQL (Type inheritance). I found
thattable inheritance is possible...but I'd like to do it on types.<br /><br /> Example:<br /> define a type Value and
twosubtypes Temperature and Humidity and then define a table that has an attribute of Value type (that can accept both
specializedtypes).<br /><br /> Thanks
