RE: timestamp error cant find class for type 1296

Hello Peter,

Can you explain this more in detail, because I fail to see the difference in
the following:

Welcome to the POSTGRESQL interactive sql monitor:
  Please read the file COPYRIGHT for copyright terms of POSTGRESQL
[PostgreSQL 6.5.3 on hppa1.1-hp-hpux10.20, compiled by cc -Ae ]

snlsor=> create table test2 ( id integer primary key);
NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index 'test2_pkey'
for table 'test2'
CREATE
snlsor=> create table test3 (id datetime primary key);
NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index 'test3_pkey'
for table 'test3'
CREATE

Best regards,
Roelof
