# select version();
                                                      version
-------------------------------------------------------------------------------------------------------------------
 PostgreSQL 8.1.11 on x86_64-unknown-linux-gnu, compiled by GCC gcc 
(GCC) 4.1.2 20061115 (prerelease) (SUSE Linux)

Today I dropped an index:
DROP INDEX dbmail_messageblks_physmessage_idx ;

The table is now:
# \d dbmail_messageblks
                              Tabelle »public.dbmail_messageblks«
     Spalte      |   Typ    |                            Attribute
-----------------+----------+------------------------------------------------------------------
 messageblk_idnr | bigint   | not null default 
nextval('dbmail_messageblk_idnr_seq'::regclass)
 physmessage_id  | bigint   |
 messageblk      | bytea    | not null
 blocksize       | bigint   | not null default (0)::bigint
 is_header       | smallint | not null default (0)::smallint
Indexe:
    »dbmail_messageblks_pkey« PRIMARY KEY, btree (messageblk_idnr)
    »dbmail_messageblks_physmessage_is_header_idx« btree 
(physmessage_id, is_header) CLUSTER
Fremdschlüssel-Constraints:
    »dbmail_messageblks_physmessage_id_fkey« FOREIGN KEY 
(physmessage_id) REFERENCES dbmail_physmessage(id) ON UPDATE CASCADE ON 
DELETE CASCADE

And immediately after the drop I got this:
DELETE:ERROR:  could not open relation with OID 102021
DELETE:CONTEXT:  SQL statement "DELETE FROM ONLY 
"public"."dbmail_messageblks" WHERE "physmessage_id" = $1"

for each and every delete of a row in that table. After a
REINDEX TABLE dbmail_messageblks;
everything seems to work.

Is that a bug or did I do something bad?

I was wrong, still get this error:
Dec 18 10:55:33 db2.zmi.at postgres[2816]: [112-1] DELETE:ERROR:  could 
not open relation with OID 102021
Dec 18 10:55:33 db2.zmi.at postgres[2816]: [112-2] DELETE:CONTEXT:  SQL 
statement "DELETE FROM ONLY "public"."dbmail_messageblks"

how can I get rid of it? A vacuum and reindex table was already done, 
still...

Does it persist if you close the connection and open a new one?

You're great, that worked indeed. I was a bit nervous now ;-) Thanks!
