Re: Table space grow big - PostgreSQL

I'm agree with ian.
There is something strange with your filesys...

Can you exec an 'ls -la' ? Perhaps somebody has move something else in
that folder with hidden name ( with a dot in folder name )
And, of course, a fsck should be advisable. :)

I'm still confused about the disk space, even more so now that more
servers and figures of 1Gb and 15Gb have joined the party.

Presumably this:

> 3.6M ./1
> 3.6M ./16975
> 51G ./95186722
> 4.8M ./4830693
> 51G .

is the output from some $ du command. And is this

the output from some $ ls command on
/usr/local/pgsql/data/base/95186722? You say there is nothing else in
that directory, but those sizes don't add up to 51Gb so something is
messed up somewhere.

Maybe this is nothing to do with postgres and a reboot and/or fsck of
the disk will fix everything.
