WAL-G Zstd compression seems to be unavailable

[EraYaN]

Gives the error:

failed to configure compression: Unknown compression method, supported methods are: [lz4 lzma brotli]

when trying to set WALG_COMPRESSION_METHOD to zstd. The WAL-G project still seems to ship zstd, they even moved to a full Go implementation about a week ago, is there a reason the spilo image does not ship it?

[hughcapet]

As far as I understand, zstd compression is not yet included into any WAL-G release. Spilo uses the latest release version, not the current state of WAL-G project's master branch

[EraYaN]

Aah I assumed it would have shipped already since the code in WAL-G is from 2018 and the latest release was much more recent. Like this is the original PR: wal-g/wal-g#99

[hughcapet]

and it was disabled in 2018: wal-g/wal-g@a27a2a9
returned only recently: wal-g/wal-g@25616a7

Aah that is unfortunate, we'll go run Brotli in the mean time.

#986 will fix that 😄

[gabrielmocan]

@EraYaN I can confirm zstd is now working after #986

Cheers!
