If you want more detail than is in the release notes, look at the SGML source for the notes to see the commit references, for example <listitem> <!-- Author: Noah Misch <noah@xxxxxxxxxxxx> Branch: master [ab0ed6153] 2018-08-31 22:59:58 -0700 Branch: REL_11_STABLE Release: REL_11_0 [ee0ab2754] 2018-08-31 23:00:01 -0700 Branch: REL_10_STABLE [1664c8b30] 2018-08-31 23:00:01 -0700 Branch: REL9_6_STABLE [081e4104a] 2018-08-31 23:00:02 -0700 Branch: REL9_5_STABLE [e3eca937c] 2018-08-31 23:00:02 -0700 Branch: REL9_4_STABLE [20cd88857] 2018-08-31 23:00:03 -0700 --> <para> Fix unexpected timeouts when using <varname>wal_sender_timeout</varname> on a slow server (Noah Misch) </para> </listitem> and then you can look at, eg, https://git.postgresql.org/gitweb/?p=postgresql.git&a=commitdiff&h=081e4104a (or do "git show 081e4104a" in a git checkout) to see the commit log message and the actual code changes. For the last year or so, the policy has been to include these commit reference comments in every relevant branch's release-m.n.sgml file. Before that you had to dig around a little, because in the interests of space I only included them in the newest released branch. (So for example the above is from the v10 branch; v11 was not yet released so it had no release note for this.) As Adrian mentions, grepping the result of "git log" is also a good way to find relevant commits. regards, tom lane
