Ok. I don't have the disk space to migrate to 7.3 right now.
Our database is about 500 million tuples with about 100 fields.
However, I checked out the beta source and noticed the following new
lines near line 934 in src/backend/access/rtree/rtree.c in 7.2.2:
+ pfree(DatumGetPointer(union_dl));
+ pfree(DatumGetPointer(union_dr));
Looks like a leak fix to me. Patching these in, I found that the leak
is much reduced; still looks like a tiny leak remains. We will try
7.3beta asap.
Thanks.
