Michael Richards (michael(at)fastmail(dot)ca) reports a bug with a severity of 4
The lower the number the more severe it is.
Short Description
SQL function lo_unlink is not documented
Long Description
http://postgresql.readysetnet.com/users-lounge/docs/7.1/programmer/lo-funcs.html
Says:
There are two built-in registered functions, lo_import and lo_export which are convenient for use in SQL queries. Here is an example of their use
CREATE TABLE image (
name text,
raster oid
);
INSERT INTO image (name, raster)
VALUES ('beautiful image', lo_import('/etc/motd'));
SELECT lo_export(image.raster, '/tmp/motd') from image
WHERE name = 'beautiful image';
This should also document the lo_unlink function as being able to remove these BLOBs is also supported. See below.
Sample Code
urdr=# select lo_unlink(6816289);
lo_unlink
-----------
1
(1 row)
