Update to default compression algorithm for Heroku Postgres WAL compression
We changed the default compression algorithm for the Heroku Data Labs WAL compression feature. The new algorithms are more performant for WAL compression. The default compression algorithm depends on the Heroku Postgres plan : Heroku Postgres databases on -5 and higher plans use ztsd . Heroku Postgres databases on -4 and lower plans use lz4 .
