I imagine that there is strong evolutionary pressure pushing minority platforms in the direction of bug-compatible-with-glibc. There is definitely a similar trend around things like endianness and alignment pickiness. But it wasn't always so. It seems fair to wonder if AIX bucks the glibc-compatible trend because it is already on the verge of extinction. If it wasn't just about dead already then somebody would have gone to the trouble of making it bug-compatible-with-glibc by now. (To be clear, I'm not arguing that this is a good thing.) Maybe it is still worth hanging on to AIX support for the time being, but it would be nice to have some idea of where we *will* finally draw the line. If the complaints from Andres aren't a good enough reason now, then what other hypothetical reasons might be good enough in the future? It seems fairly likely that Postgres desupporting AIX will happen (say) at some time in the next decade, no matter what happens today. -- Peter Geoghegan
