Hello.

Recently some users started to complain about:
Warning: PostgresSQL query failed: FATAL 1: btree: lost page in the chain of duplicates

I noticed that VACUUM removes this problem, but no making
VACUUM I've got:
NOTICE: BlowawayRelationBuffers(confread, 45): block 154 is referenced (private 0, last 0,
global 1)
FATAL 1: VACUUM (vc_rpfheap): BlowawayRelationBuffers returned -2

What it can be? I'm using 6.3.2

A relatively old version of PostgreSQL...upgrade to v6.4.2, as I
believe this was fixed several months ago, in v6.4...
