I don't know if this is a bug and if so, if it fixed in the most current patch. (I don't see anything in the release notes that make think so though however).
I have yet to be able to create a small self contained case to reproduce for the bugs mailing list so someone can look into it.

We are facing this issue with 8.3.8 PG version and we don't use cursors. Is it a bug with PG, if so can you please provide the bug details.
