Reproduced here. Once the system reaches a state where it's leaking (which happens only occasionally for me during installcheck-parallel), it keeps leaking for future SSI transactions. The cause is SxactGlobalXmin getting stuck. The attached fixes it for me. I can't remember why on earth I made that change, but it is quite clearly wrong: you have to check every transaction, or you might never advance SxactGlobalXmin. -- Thomas Munro https://enterprisedb.com
