[GENERAL] Enhancement proposal - detect chain of triggers from inside the trigger

[Edson Richter]

I was wondering, would be a nice addition the ability to read the chain 
of triggers (may be another trigger variable like TG_OP, called 
"TG_CHAIN" or something else that will be an array with the name of the 
triggers called before current trigger).

Would help debug database triggers that have cascaded events.
Regards,

Edson
