vacuum: invalid memory alloc request size 2684354556 - Mailing list pgsql-bugs

Hi,

i have
- PostgreSQL 8.1.3 on x86_64-unknown-linux-gnu, compiled by GCC gcc
(GCC) 3.3.5 20050117 (prerelease) (SuSE Linux)
- 2 services running, one on port 5432 and another one on port 5431.

vacuum fails in every way i tried (psql, pgadmin, autovac, jdbc;
single table, whole database) but analyze and vacuum full works fine.
it doesn't matter which server or which database i try.

the message i get is:
  FEHLER:  invalid memory alloc request size 2684354556

i already got exactly the same exception with 8.1.1, i've got an
update from 8.1.1 to 8.1.3 on monday.
the exception apears to be unchanged.

the server crashed quite often.

and i have some lines from my logfile
