But i modify too Natts_pg_class and the Anum macro...Only I forgot mentionated it in the last mail. i put:
#define Natts_pg_class_fixed 25
#define Natts_pg_class 26
....
#define Anum_pg_class_myNewAttribute 25
#define Anum_pg_class_relacl 26
#define Natts_pg_class 26
....
#define Anum_pg_class_myNewAttribute 25
#define Anum_pg_class_relacl 26
I really don't understand you when you said: "there was some
cruftiness involved there in existing releases (it's gone in HEAD
and I'm too lazy to look back at exactly what it was...)"...
Anyway, thanks for trying to help me....
P.D: For anyone, i still need help.... Bye.

Did you remember to update Natts_pg_class and the Anum_ macros?

Seriously ugly, should use offsetof the last attribute, ie, yours.
Also, look at the uses of Natts_pg_class_fixed --- there was some
cruftiness involved there in existing releases (it's gone in HEAD
and I'm too lazy to look back at exactly what it was...)
