Re: database corruption

There are no filesystem level content size restrictions that I am aware
of on this system.  The user pgsql should have full access to the
filesystems indicated except for the root filesystem.

Where is the temporary location?  I am searching around to see if I can
specify it anywhere in the config files but can't seem to find anything
which leads me to believe that its part of the postgres data directory.

I guess the first question is, does the db have permissions(access) to
all that
space?
