Support for external toast datums, as of 36820250, so that should be independent on the compression method used, no? I was just sticking some checks based on pg_column_compression() all over the test, and all the values are correctly getting compressed and decompressed as far as I can see. I got to wonder whether this is not pointing at an actual issue, and whether it may be better to not make this test rely only on pglz, but I have not put much thoughts into it TBH. -- Michael
