Re: commit callback, request, SOLVED

Hi!
I have needed deferrable check, but it is not implemented. I thought, 
the deferrable trigger is the solution, but it is exists only for 
referential integrity. I have started to study the postgresql source 
code for implementing deferrable triggers for any purpose.

Now i try the constraint trigger, and it is good for using instead of 
deferrable check, but it is not intended general use.
In the documentation:
"CREATE CONSTRAINT TRIGGER is used within CREATE TABLE/ALTER TABLE and 
by pg_dump to create the special triggers for referential integrity. It 
is not intended for general use."

My question is, may i use it for this purpose (instead of deferrable 
check)?
What means "it is not intended for generally use"?
