Hi,
I've changed the large object memory managment strategy to ensure that
each large object has it's own memory context.
This way I can free all memory for a large object when I lo_close
is called for it's oid. This seems to work.
I've noticed that the heap_close function used to close the heap used
by a large object doesn't really do any thing. (It calls RelationClose
which decrements some reference count).
Somehow I have to free the relation from the cache in the following
situations:
1. In a transaction I must free the stuff when the transaction is
commited/aborted.
2. Otherwise it must happen when lo_close is called.
Is this right?
Can anyone point me in the right direction?
Thanks Maurice.
