You may want to try to reindex the associated toast table and see if
that clears it up.
To get the name of the associated toast table, you may run this query:
select relname from pg_class where oid =
(select reltoastrelid from pg_class where relname = 'maps');
Then, reindex it.
reindex table "toast table name" ..

Greetings...
I'm getting an error. The error says...
places=# REINDEX INDEX maps_map_id_seq;
ERROR: "maps_map_id_seq" is not an index
places=# SELECT * FROM maps;
ERROR: missing chunk number 0 for toast value 131343627
I have tried reindexing the index, the table, and the database. I
continue to get this error. What can I do to recover from this.

PS Let me say that I know this is my fault. This index is very
bloated. Yesterday, I tried to vacuum. I got errors because
max_fsm_pages what set at a number that was too small.

When I ran the query you specified I got relname of "pg_toast_16429. When I ran the REINDEX TABLE pg_toast_16429 the system responds that relation "pg_toast_16429" does not exist.

I think it should be pg_toast.pg_toast_16429 so: REINDEX TABLE pg_toast.pg_toast_16429; check relnamespace in pg_class for this table, and check it against pg_namespace to be sure. depesz
This gives the same error. I can select columns from the table although select * gets the error. I tried making a copy of the "maps" table using CREATE TABLE new table name (all columns) AS SELECT all columns FROM maps; This also gave me the same error.
