Обсуждение: VACUUM (vc_rpfheap): BlowawayRelationBuffers returned -2

Hi all,

I noticed that vacuum didnot run correctly, I got following message:


VACUUM
NOTICE:  BlowawayRelationBuffers(invoices, 26): block 27 is referenced
(private 0, last 0, global 1)
FATAL 1:  VACUUM (vc_rpfheap): BlowawayRelationBuffers returned -2


Next time I start vacuum, I see this:
ERROR:  can't create lock file -- another vacuum cleaner running?

 Should I get worried and keep my backup close at hand?

This means that 27 block of invoices was referenced by some
other backend (but shouldn't!)
Unfortunately, I can't reproduce this error... :(
BTW, how many connections were present when vacuum was running?

rm pg_vlock file...

Also, I don't know is this in FAQ or not: after getting FATAL
you should restart postmaster.

Nothing should be broken by this error...

Hopefully, none.  Vacuum is ran from a background process that collects data
all day, and around midnight it does a dump_all and after that a vacuum.
