ERROR: missing chunk number 0 for toast value 1821556134 in pg_toast_17881

Greetings and salutations.

I've got some weirdness.

Current:
Postgres 9.3.4
Slony 2.2.3
CentOS 6.5

Prior running Postgres 9.1.2 w/slony 2.1.3 CentOS 6.2

I found that if I tried to run a vacuum full on 1 table that I recently
reindexed (out of possibly 8 tables) that I get this error:

# vacuum full table.ads;

ERROR: missing chunk number 0 for toast value 1821556134 in pg_toast_17881

If I run a vacuum analyze it completes fine, but I can't run a vacuum full
without it throwing an error. I seem to be able to query the table and I
seem to be able to add data to the table and slony seems fine as does
postgres.

I'm unclear why the vacuum full is failing with this error. I've done some
searching and there are hints to prior bugs, but I didn't catch anything in
9.3.3 to 9.3.7 that talks about this.

My next steps without your fine assistance, will be to drop the table from
slon and re-add it (meaning it will drop the table completely from this db
and recreate it from the master (there we can do a vacuum full without
failure)..

I have already tried to remove the indexes and just create those, but no
luck.

Ideas?

Thanks
