UPD: Attached results are not correct. The environment was not tuned correctly and I get too often checkpoints for runs without WAL compression and this leads to bad results for "compdisabled" runs. But I've benchmarked it again later and there is still performance boost about 20-30% on our synthetic tests on our environment.

> We already have page compression implementation, so we can extend this approach to compress WAL page snapshot records (leaving other record types uncompressed) at relatively low cost.
