Tablespace Problem

I have found a problem in my database. The following error occurs

sometime

not any specific database operation.

ERROR:XX000:count not create temporary file
"pg_tblspc/86014/pgsql_tmp/pgsql_tmp3568.0":No
such file or directory.

Does that pgsql_tmp directory exist? If not, does its parent directory
have the right ownership and permissions to let the server create it?

Note that pg_tblspc/86014 is presumably a symlink --- you need to look
at the directory the symlink points to.

Hi,
Sir,
I have been checked pg_tblspc/86014 directory have no permission to
create new folder.
I am using Windows XP Os and VB.Net frontend. I created the tablespace
folder by programaticaly using vb.net.

I tried to chang the user permission for that folder by programatically
and manualy using properties of the folder in windows explorer but folder
permission not changed.
Is there any option to solve this problem via postgersql?

If not , Should I change the folder permission for which user? current user
or service account for postgresql.

the Postgresql account needs to have full control over all its directories

No other account needs access to postgresql directories.

If security does not read as postgres account having full control and you
can't change security, You need to take ownership of the directories first
then you can change security.

To take ownership you have to be admin on that computer. Then put postgres
account as full control.

Postgresql account does not need to own the directory just have full
control. If you can't change security settings or take/assign ownership
then the account doing this is not a Administrative account, or security up
the chain of directories has some mighty odd settings which means resetting
each directory up the chain one at a time to you reach the root. The
process is take owner ship then rest security to what it was originally.

As your in the Program Files directory tread lightly because security can
block service accounts Local Services, System & Network making the machine
unbootable

When you installed PostgreSQL the windows account postgres should have been
created and put into the User group with the option to log in as a Service.

What account is Postgresql using to start under, if postgres does not exist
???

What ever account the service Postgresql is using to start up under needs
to have full control of
c:/program files/progresql
and what ever table space directories there are created.

if the table spaces are on another Drive make sure the root has the
account/group postgres is in has permissions to list directories, and
contents. If not the account will be blocked from reading the drive
contents regardless what child directories security states.

Sir,

I have tried to change the ownership of the postgres directories to
postgresql account.
But in windows , the posgresql account has no permission to take ownership
of any directory.
Because the postgresql service account is not under any group and not as a
logon account.
How can I set ownership for postgres account?

Thanks in advance.
