And how could i fix it. You have probably a corrupted toast index on a table. Try to reindex it and if that doesn't help hunt down the damaged main row and update it's toasted value with something fresh (there have been enough discussions about it, you should find how to do that in the mailing list archives. These discussions will also point out that you probably have some bad memory and/or other non trustworthy piece of hardware including the tools you should use to identify the damage.

How can I discover which toast table referenced to a phisic table? example: table name tbdmovimento. how could i know the toast table name to reindex it. tnx. Eric Anderson Martins Miranda Net Admin @ Via Net SAO

Look at the base table's pg_class row. reltoastrelid is the OID of the
corresponding toast table. So, for example, if I thought "text_tbl" had
such a problem:
regression=# select relname from pg_class where
regression-# oid = (select reltoastrelid from pg_class where relname = 'text_tbl'); relname
-----------------pg_toast_163219
(1 row)
regression=# reindex table pg_toast.pg_toast_163219;
REINDEX
regression=#

how can I alter the column width i´ve tried alter table tablename alter columnname varchar(2) but it returns errors tnx. Eric Anderson Martins Miranda Net Admin @ Via Net SAO
when i try that i´v got an error ERROR: "pg_toast_26474986" is a system table. call REINDEX under standalone postgres with -O -P options so I kill postmaster and up it standalone. but the reindex command doesn´t have options. and postmaster doesn´t have these ones too. tnx.
