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.
