Hi all. =C2=A0 I have a pg_largeobject of ~300GB size and when I run "vacuu=
mlo -n=20
<dbname>", I get: =C2=A0 Would remove 82172 large objects from database "<d=
bname>". =C2=A0
So I'm running without "-n" to do the actual work, but it seems to take=20
forever. The disks are 8 SAS 10K HDD drives in RAID5. =C2=A0 Any hints on h=
ow long=20
this is supposed to take? =C2=A0 Thanks. =C2=A0 -- Andreas Joseph Krogh CTO=
