Hi, Brandan,

You need a shell script as restore command that does both uncompressing
the current file, and starting a background decompress of the next
file(s). It also has to check whether the current file is already in
progress from a last run, and wait until this is finished instead of
decompressing it. Seems to be a little complicated than it sounds first.

Warning: Don't do it this way!
It will break things because PostgreSQL will try to access a
not-completely-restored wal file.
HTH,
