Thread: Failing lo_import on RH 5.1 -- postgresql-6.3.2 (please help-I'm on my knees..)

Here is something I totally don't understand. And i need this one to be
fixed...

Here is a transcript of a session, with a test-table containing only
one oid-column....

    [jeroen@rulgfu sql]$ psql -f test.sql
    insert into testfile values (lo_import('test.sql'));
    ERROR:  be_lo_import: can't open unix file"test.sql"

    EOF
    [jeroen@rulgfu sql]$ ls -l test.sql
    -rw-r--r--   1 jeroen  postgres       53 Nov 12 15:48 test.sql
    [jeroen@rulgfu sql]$ cat test.sql
    insert into testfile values (lo_import('test.sql'));

First I thought it was the permissions... but not at all... look above

Then I thought, well, on my old slackware box it ran beautifully... so
let's try that (self-compiled) version (6.3.3 i believe....)... but no
difference.

Does anybody have a clue (please???)

Thanks in advance!!!!!

Not sure, but try putting the file on the same machine that your backend runs,
e.g. the /tmp directory of the machine that the backend is installed.

Hope it helps.

It's a pity. It's on the same machine.

Thanks anyway

Somebody else?

I tried to do lo_import from psql... it worked under 6.3.2 but I couldn't
do a lo_export...

I'd love to be able to do this too... must be form psql though.... if
anyone could let me know if that's possible and give me the syntax I'd be
greatful.

Cheers....

My Windows unders~1 long filena~1, and yours?

       [jeroen@rulgfu sql]$ psql -f test.sql
       insert into testfile values (lo_import('test.sql'));
       ERROR:  be_lo_import: can't open unix file"test.sql"

Isn't the problem that the backend expects test.sql to be in the data
directories somewhere?  Try a full path.

Good guess. Nevertheless, didn't work.

I think it is broken, but we will have a patch soon.

I'm staying tuned!!

Bot how do you explain /boot/vmlinuz can be imported prefectly?

I found the problem:
RH 5.1 sets the home directories unsearchable by others.
Setting chmod ag+x <home-dir> helped
Full paths are needed.

Thanks a lot everyone!!

And oh... I've applied the patch. Anyone interested in the regression
results?
