Обсуждение: failed to re-find parent key in "..." for deletion target page

I was doing some testing with tsearch2 on my dev box and I've run
across this problem.

I created the tsvector and added the trigger and then i was updating
the entire table to populate the ixdfti field.   When i was done, I
was unable to vacuum the table, I get this error.   Any ideas an
what's going on?  I've shutdown the database and made a tar of it
incase there is additional info you need.

basement_dev=# update developer_name set developer_id = developer_id;
UPDATE 262083
basement_dev=# VACUUM FULL developer_name;

Oh dear, I thought we'd fixed that.

Can you send me copies of this index file ... and preferably the
underlying table too?

You should be able to get out of it by REINDEXing, but we need to find
the cause first.

            regards, tom lane

Any news on this?

Unfortunately, I wasn't able to get Tom the requested files.
