Thread: Error: missing chunk number for toast value

Hi All;

We're seeing this error in our 8.3.9 database:

# select * from comments;
ERROR:  missing chunk number 0 for toast value 1274882 in pg_toast_49234


I tried this:

# reindex table pg_toast.pg_toast_49234;
REINDEX


but the error still persists.

Thoughts?

Your database is corrupted.  Any idea how that happened?  As with
any database corruption, I recommend you stop the server and make a
copy of the whole data directory and everything under it before any
recovery attempts.

You could zero in on the damage by selecting specific columns, and
ranges of rows.

A little more detail would be helpful.  For ideas, read this:
