Thread: lo_export -- permission denied

Hi,

i followed this
(http://designmagick.50megs.com/postgresql-tutorial/file.html) tutorial
to import/export files to/from PostgreSQL. It all works fine on my
Notebook, but when I try to put it on another machine,

"select lo_export(OID,'path/on/local/disc')"

comes up with an error:

Warning : PostgreSQL query failed: ERROR: lo_export: can't open unix
file "/path/to/local/disc/filename": Permission denied in
/path/to/php_files/file_retrieve.php on line 64

It works fine when I change the local output path to /tmp, but it fails
when the path is under the webserver root. I checked/compared all
file/diretory permissions on both machines, they're all the same.

Any suggestions ?

Regards
ALEX

Is the backend being run as the same user id in both machines?
