Hello,
I am running PostgreSQL v7.2.1 under RedHat 7.3.
I have a database of three or four tables with several
million records.
I have been getting minor (repairable) data corruption on a
regular basis. This is where some field's contents get
partially changed to funny characters.
Until yesterday, I was able to access those rows and delete
those records.
The data corruption has gotten so bad that I no longer can
access certain records. Therefore it fails most of my
production operations. Also the vacuum keeps failing now.
Vacuum Error Message:
----------------------------------------------
NOTICE: Analyzing pg_rewrite
NOTICE: --Relation urls--
ERROR: XLogFlush: request 16/E6B686EC is not satisfied ---
flushed only to 16/E6B680E4
vacuumdb: vacuum xxxxxx failed
----------------------------------------------
PG_DUMP Error Message
----------------------------------------------
pg_dump xxxxx > backup/xxxxxx-072102.sql
pg_dump: ERROR: MemoryContextAlloc: invalid request size
1919435556
pg_dump: lost synchronization with server, resetting
connection
pg_dump: SQL command to dump the contents of table "test"
failed: PQendcopy() failed.
pg_dump: Error message from server: pg_dump: The command
was: COPY "docs" TO stdout;
----------------------------------------------
As far as the size of my database is concerned, it is well
below 1Gig.
I seriously considering downgrading to lower release of
postgres.
Thanks,
