Not experienced with Postgres and its ecosystem unfortunately, but all those Postgres extensions popping up on hn lately certainly make me envious. To someone with more insight: How risky is it to rely on those extensions? I guess rust handles the 'accidental data corruption or crashes' aspect. How difficult is it to continue to use such an extension once the original author walks away? Is the extension API somewhat (or perfectly?) stable? Given that this example probably mostly used in CHECK contraints, I guess it could be fairly easy removed or replaced from a running installation?
