Hm, is there any chance the COPY targets more than one partition? If so, this sounds like it might be the issue described here https://postgr.es/m/20230925213746.fwqauhhifjgefyzk%40alap3.anarazel.de I think at this stage the easiest fix might be just to copy the approach of calling ReleaseBulkInsertStatePin(), even though I think that's architecturally wrong.
