The way I read it there is now way to reproduce this as the codepath used in
the fuzzer ins't present in postgres (PGLZ_strategy_always is not used by any
callsite).
Whether or not there is a bug in the compression code, or PGLZ_strategy_always
being incorrectly defined, or none of the above, remains to be seen.
