Thread: unexpected chunk number

unexpected chunk number

From

hello all

When i tried ´pg_dump -v -f dump.dmp dtbtransporte´ I got the error:

pg_dump: restoring data for table tbdmovimento

pg_dump: dumping out the contents of table tbdmovimento

pg_dump: ERROR: unexpected chunk number 8 (expected 0) for toast value 6935693

pg_dump: lost synchronization with server, resetting connection

pg_dump: SQL command to dump the contents of table "tbdmovimento" failed: PQendcopy() failed.

pg_dump: Error message from server: pg_dump: The command was: COPY "tbdmovimento" TO stdout;

pg_dump: *** aborted because of error

 

So I´ve ran a query to see which pg_toast from this tbdmovimento

So I shutdown de postmaster and up a standalone backend and reindexed the database (REINDEX DATABASE dtbtransporte FORCE). All this after a vacuum analyze.

How the pg_dump still returns above error, I´ve tried to REINDEX the index pg_toast_16557. Reindex ran ok, but the pg_dump still returns this error.

 

any ideas.

tnx

Eric

Hm.  Could we see the results of

select chunk_seq,length(chunk_data) from <tbdmovimento's toast table>
where chunk_id = 6935693;

If you are not trusting the index then it might be good to try this
with enable_indexscan turned off and see if you get the same answers.

            regards, tom lane

it generates following error:

ERROR: Function 'lenght(bytea)' does not exist

Unable to identify a function that satisfies the given argument types

You may need to add explicit typecasts



this row is only which has chunk_seq = 8.

why couldn´t I simply UPDATE it?

tnx

Eric

sorry about dumb ´lenght´ instead ´length´.

the length of chunk_data is 255.

tnx.

I tried setting enable_indexcan off

and got same error:

dump the contents of table tbdmovimento

pg_dump: dumping out triggers

pg_dump: dumping out rules

pg_dump: creating TABLE tbdmovimento

pg_dump: restoring data for table tbdmovimento

pg_dump: dumping out the contents of table tbdmovimento

pg_dump: ERROR: unexpected chunk number 8 (expected 0) for toast value
6935693

pg_dump: lost synchronization with server, resetting connection

pg_dump: SQL command to dump the contents of table "tbdmovimento" failed:
PQendcopy() failed.

pg_dump: Error message from server: pg_dump: The command was: COPY
"tbdmovimento" TO stdout;

pg_dump: *** aborted because of error

why can´t I simply update chunk_seq from 8 to 0?

tnx
