Thanks for the suggestions Scott.

I was looking at the zero_damage_page option and enabled it in my postgres.conf.  I saw that it detected bad pages and zero'd them out during a number of reindex and a vacuum's.

Now when i reindex though,  I am getting this error.

NOTICE:  table "pg_foreign_server" was reindexedERROR:  could not create unique index "pg_toast_57366_index"
DETAIL:  Table contains duplicated values.

ERROR:  could not create unique index "pg_toast_57366_index"
DETAIL:  Table contains duplicated values.

I was wondering if anyone had any suggestions on how to resolve this
issue...  I am moving otrs to another server and during the backup process I
am running into this error

pg_dump: dumping contents of table article_attachment





pg_dump: SQL command failed

pg_dump: Error message from server: ERROR:  unexpected chunk number 7

pg_dump: The command was: COPY public.article_attachment (id, article_id,
filename, content_size, content_type, content, create_time, create_by,
change_time, change_by, content_id, content_alternative) TO stdout;





pg_dump: *** aborted because of error





I have tried a vacuum and reindex with no successes.

You'll likely have to figure which blocks are corrupted, and copy out
the good data using a where clause the excludes it, then get what you
can out of it, truncate the table, and reinsert the data.

Then figure out what part of your hardware is / might be dodgy.  mem
test, disk check, etc.
