Hello,
I've just started working with ordbms. I'm searching for differences between
postgresql and oracle...

Btw, I've found it's possible to declare a method for a specific type in
oracle...so if I create a type MyType, I can associate it also a method
MyMethod....using the costructors:

CREATE TYPE MyType AS OBJECT
(
...
...
...
MEMBER FUNCTION MyMethod(parameterName  parameterType)
RETURN ReturnType);

Is it possible to do the same with postgreSql? I've found the CREATE
FUNCTION command...but it seems it creates global functions, not associated
to a particular type...

Thanks
