Thread: Can't find a default operator class for type 1296.

This occured when I was creating a table:

---------------snip-----------------------------------------------
CREATE TABLE kurse (
  wkn    text      NOT NULL,
  datum  timestamp NOT NULL,
  ausg   float4,
  rueckn float4,
  zg     float4,
  aussch float4,
  PRIMARY KEY (wkn,datum)
);
NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index 'kurse_pkey' for table 'kurse'
ERROR:  Can't find a default operator class for type 1296.
wp=> SELECT version();
version
-------------------------------------------------------------
PostgreSQL 6.5.3 on i686-pc-linux-gnu, compiled by gcc 2.95.2
(1 row)
---------------snip-----------------------------------------------

Changing 'datum' to type datetime helps, but datetime is deprecated in
PostgreSQL 7.0.

Does this work in 7.0 beta?

Yes.

As I understand it, all the 'timestamp' code came from 'datetime'. The old
'timestamp' was a little stupid, so to say.
