Hi all,
I'm trying to write a trigger that converts integer to bytea.
My schema is like this:
Create table xx (
id int,
...
data bytea);
the first 3 bytes of data are the binary representation of id
(id is extracted from data by the application)
I can occur that id change in that case

Is there an other way? (preferabily simple :)
This kind of question would be more appropriate on pgsql-general.
What do you want the resulting bytea to look like?

example : id = 9 , bytea = '\000\000\011' IIRC
What do you expect to happen when server and client are differently-endian?

Does it matter if you have written an explicit cast for int to bytea?

Hi,
please don't top post to someone who didn't used this convention

2) i know what a byte order is , i just thought your interface i.e.
libpq would convert it to the local byte order.
You haven't thought this through. Data traveling over libpq is still
text, not binary, in most cases, so byte order is irrelevant at that
time. The
