deleting large objects from jdbc

Hi,

I've been browsing the newsgroup archives and came across the following:

Does this mean that to delete my large object I need to delete the row 
in my table, and also the row or rows in pg_largeobject. Currently I am 
only deleting the row in my table. I have just been looking at the 
pg_largeobject table, it seems to have more rows than I would expect in 
it. Is the solution to pass these two commands to jdbc?
delete from my_table where lob_oid = 1234
delete from pg_largeobject where loid = 1234

Thanks in advance
Heather.
