ERROR: invalid overflow block number 13947

Hi,

During execution of query 
UPDATE links SET weight = weight + (0.002972378315) WHERE ot='38933058' AND
k='39267613'

I got the error: ERROR:  invalid overflow block number 13947

The "links" table have two HASH indexes and one BTREE index.
Reindexing of "links" table is in progress. But I'm not sure will this resolve
this problem ?
PgSQL 8.1.3 on FreeBSD


Good luck,
Michael
