Do you know if the old travis build environment had liblz4 installed ? I'm asking regarding Dilip's patch, which was getting to "check world" 2 weeks ago but now failing to even compile, not apparently due to any change in the patch. Also, are the historic logs available somewhere ? http://cfbot.cputube.org/dilip-kumar.html
Also, what's the process for having new libraries installed in the CI environment ? There's 3 compression patches going around, so I think eventually we'll ask to get libzstd-devel (for libpq and pg_dump) and liblz4-devel (for toast and libpq). Maybe all compression methods would be supported in each place - I hope the patches will share common code. -- Justin
