PostgreSQL version: 7.4.6
Operating system: RedHat ES release 3, x86_64
Description: "unexpected chunk number" during pg_dump
Details:
Our regular pg_dump aborted this afternoon with this output:
pg_dump: ERROR: unexpected chunk number 0 (expected 1) for toast value
4294879152
pg_dump: SQL command to dump the contents of table "dataset_cache" failed:
PQendcopy() failed.
pg_dump: Error message from server: ERROR: unexpected chunk number 0
(expected 1) for toast value 4294879152
pg_dump: The command was: COPY public.dataset_cache (checksum, version_no,
bind_params, sql_statement, serialized_value, date_created) TO stdout;
pg_dump: *** aborted because of error
We saw the same message when we tried to cluster the effective table. The
problem went away after truncating the table.
I've searched the pgsql-bugs archives and found reports of this problem, but
haven't seen a solution. Is there a solution to keep this from happening in
the future? (Version upgrade maybe?)
