Well actually you did yourself a disservice by including the EXCEPT
code. That changed the error message. Taking that code out and running
the failing function you get:
test-> validateSession('441122','10.11.12.13','abc',3600,3600);
ERROR: column reference "session_id" is ambiguous
LINE 2: session_id=session_id and session_ip=client_ip
^
DETAIL: It could refer to either a PL/pgSQL variable or a table column.
QUERY: select * from app_val_session_vw where
session_id=session_id and session_ip=client_ip
CONTEXT: PL/pgSQL function
validatesession(character,inet,character,bigint,bigint) line 7 at SQL
statement
I would say that is fairly specific:)
