Subject: Split clients: improved calculation of range boundaries
X-Git-Tag: release-1.31.2~15
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/static/gitweb.js?a=commitdiff_plain;h=d994f5b8220847eb8f7e4400be5f7e6eb4538e46;p=nginx.git

Split clients: improved calculation of range boundaries

If the last variant was given an explicit percentage to reach 100%, it
did not cover hash values on the range boundary or due to accumulating
rounding error.  Now this corresponds to the configuration with "*".
