CREATE TRIGGER trigger_name [BEFORE | AFTER] event ON table_name
FOR EACH ROW EXECUTE PROCEDURE function_name();

I can do

SELECT * FROM pg_proc;
SELECT * FROM pg_trigger;

select * from pg_trigger,pg_proc where tgfoid=pg_proc.oid;

I can do

SELECT * FROM pg_proc;
SELECT * FROM pg_trigger;

to list all the name of triggers and functions. But I don't know which
trigger
execute which function. How do I find out that?

Thank Q very much in advance!

You could use "pg_dump -s > mydb.dmp" to dump the database schema. Then
open mydb.dmp in a text editor. I think this will show you all the
details you need.

HTH,
