Sorry, but I already killed the process to try to follow Matthias' suggestion.
I have a core file from "gcore" but it looks like it's incomplete and the
address is now "out of bounds"...
#2 0x00000000004fd9bf in lazy_scan_prune (vacrel=vacrel@entry=0x1d1b390, buf=buf@entry=14138, blkno=blkno@entry=75,
page=page@entry=0x2aaab2089e00<Address 0x2aaab2089e00 out of bounds>,
I saved a copy of the datadir, but a manual "vacuum" doesn't trigger the
problem. So if Matthias' theory is right, it seems like there may be a race
condition. Maybe that goes without saying.
