Обсуждение: lo_import problems

Hi,
   I'm trying to write an script in Perl5 that do an lo_import, but
using the one that the perl interface offers returns an oid equal to
zero:

...
$conn = Pg::connectdb("dbname=test");
$lobjId = $conn->lo_import($file);
...
   Where $file is the file to be imported into the database. If I try to do as in Chapter 45:

INSERT INTO image (name, raster) VALUES ('beautiful image', lo_import('/etc/motd'));
   I get the following error:

ERROR:  You must have Postgres superuser privilege to use server-side lo_import().       Anyone can use the client-side
lo_import()provided by libpq.
 
   And, indeed, this only works when logged on as superuser on the database, but not with the others.

Thanks in advance.

Is your job running?  You'd better go catch it!

lo_import, like all LO operations, has to be executed inside a
transaction block (BEGIN/END SQL commands).  This is, um, poorly
documented in the Perl interface's docs, though you can read about
it in the docs for the underlying C library libpq.
