Don't worry about the level. This should be regenerated when you regenerate
the path, but you better check. Otherwise, it should be pretty simple to
assign this  with SQL.

Where the delete_orgunit_with_data function comes in may be more apparent
from the following example which should move all children of Badjia
chiefdom up a level and then deletes Badjia (from the Sierra Leone DB).  I
did not include the loop here.


....Loop over all leaf nodes and move them up a level.

UPDATE organisationunit
SET parentid = (SELECT organisationunitid from organisationunit
WHERE path = '/ImspTQPwCqd/O6uvpzGd5pu')
WHERE path ~('/ImspTQPwCqd/O6uvpzGd5pu/YuQRtpLP10I')
AND hierarchylevel = 4;

..... Delete the Badjia which no longer has any children.

sierra-leone=# SELECT * FROM delete_orgunit_with_data('YuQRtpLP10I');
 delete_orgunit_with_data
--------------------------
                        1
(1 row)


That SQL would need to be tweaked a bit I think, but maybe its a bit
clearer?

Regards,
Jason
