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.
