After your tip, I rechecked the old logs. There, I had
"Tabelle enthält duplizierte Werte"
(table contains duplicate values)
but now the log message was
"duplizierter Schlüssel verletzt Unique-Constraint »bayes_token_pkey«"
(duplicate key violates unique constraint)
The latter message is just an INFO, though its logged as ERROR. It
happens when you try to INSERT a primary key that's already there, but
this got only logged once:
ZUSAMMENHANG: SQL-Anweisung »INSERT INTO bayes_token (id, token,
spam_count, ham_count, atime) VALUES ( $1 , $2 , $3 , $4 , $5 )«
PL/pgSQL function "put_tokens" line 18 at SQL statement
All other times just the violation was logged.
I double checked with a dump and reload to a fresh db - there is no
spoon [The Matrix], and also no duplicate values exist.
The error I got december 2006 with the duplicate values was really a
situation where values seem to have been inserted during a reload, but
before the index was there. I was just nervous and mixed the two
different warnings.
But I'd like to suggest changing the ERROR to WARNING for "duplicate key
violates unique constraint", as it's not serious - but it sounds like a
big problem.
Efharisto, Achilleas!
