It's been around, but is it trusted? I for one do not trust it. See

Needs some discussion. Has anyone actually reported corruption related to this? I don't doubt the opinion, but I do wonder why I have never seen reports of corruption related to this when people have readily reported such things in years past about pg_repack. If it (apparently) works so well in practice for so many companies, but has this bug, why not leverage what they have done and fix its bugs when it serves such an important function? The extension serves a huge need on many fronts.
