Dear Gurus,

As of v7.4, PostgreSQL supports error codes. I'd like to know if we may hope
for a version of psqlODBC that handles error codes.

I tried with PostgreSQL 7.4.1, ODBCExpress 6.0 (dated 2003 Oct) and psqlodbc
7.3.1.0 (dated 2003 May 15) and got the following (I assume useless) answer.

Also tried psqlodbc 7.3.2.4 (dated 2003 Nov 12) and the SQLGetDiagRec
function, with the same result.

  Message = "ERROR:  update or delete on \"cikk\" violates foreign key
constraint \"$1\" on \"szallitolevel_tetele\""
  Native = 7
  SQLState = "HY000"

AFAIK these error codes say something like "general error" in ODBC terms :)
This so-called state, "HY000" is not even an SQL state, unless I'm fatally
mistaken. It's some kind of ODBC state, isn't it?

Awaiting your kind response,

G.
