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:

Code:
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
