Обсуждение: vacuum fails

vacuum fails with the following error:

NOTICE:  Rel beruf: Pages 18: Changed 0, Reapped 18, Empty 0, New 0; Tup
900: Vac 565, Crash 0, UnUsed 441, MinLen 60, .
NOTICE:  Ind idx_b: Pages 17; Tuples 900: Deleted 0. Elapsed 0/0 sec.
NOTICE:  Rel beruf: Pages: 18 --> 10.
NOTICE:  BlowawayRelationBuffers(beruf, 10): block 11 is referenced
(private 0, last 0, global 1)
FATAL 1:  VACUUM (vc_vacheap): BlowawayRelationBuffers returned -2

what exactly does that mean? how do you recover from this? would i lose
data if i dump the data from this table and recreate it?

thanks

Frank - 

That is what I did and it was fine.  But Vadim told me later
that all I really had to do was shutdown the server, restart it and
re-vacuum.  You might try that first (you may also have to rm the
pesky pg_vlock in the ../data/base/whatever directory.

BlowawayRelationBuffers sounds ominous doesn't it?  It turned out
not to be so bad in my case!

Cheers,
Tom
