First-draft release notes for 10.1. 

As usual, the release notes for other branches will be made by cutting
these down, but put them up for community review first.  Note that a
fair percentage of the entries apply only to prior branches because
their issue was already fixed in 10.0.

Fix BRIN index summarization to handle concurrent table extension
correctly (&Aacute;lvaro Herrera)
</para>
<para>
Previously, a race condition allowed some table rows to be omitted from
the index. It may be necessary to reindex existing BRIN indexes to
recover from past occurrences of this problem.

<para>
Record proper dependencies when a view or rule

</para>
<para>
Lack of these dependencies could allow a column or data
type <command>DROP</command> to go through when it ought to fail,
thereby causing later uses of the view or rule to get errors.
This patch does not do anything to protect existing views/rules,
only ones created in the future.

<para>
Correctly detect hashability of range data types (Tom Lane)
</para>
<para>
The planner mistakenly assumed that any range type could be hashed
for use in hash joins or hash aggregation, but actually it must check
whether the range's subtype has hash support. This does not affect any
of the built-in range types, since they're all hashable anyway.

Prevent sharing transition states between ordered-set aggregates

This causes a crash with the built-in ordered-set aggregates, and
probably with user-written ones as well. v11 and later will include
provisions for dealing with such cases safely, but in released
branches, just disable the optimization.

<para>
In v10, failure to find the home directory while trying to
read <filename>~/.pgpass</filename> was treated as a hard error,
but it should just cause that file to not be found. Both v10 and
previous release branches made the same mistake when
reading <filename>~/.pg_service.conf</filename>, though this was less
obvious since that file is not sought unless a service name is
specified.

years ago.
