Merge ~paelzer/ubuntu/+source/postgresql-10:MRE-1833211-june2019-cosmic into ubuntu/+source/postgresql-10:ubuntu/cosmic-devel

[Christian Ehrhardt ]

[Andreas Hasenack (ahasenack)]

- tarball matches upstream, and this branch
- debian/* has changes other than the changelog
- this branch matches the bionic one with the exception of the version in d/changelog

+1 pending bileto. If bileto doesn't cooperate, I'll trigger a manual run.

review: Approve

[Andreas Hasenack (ahasenack)]

Above I meant "debian/* has *no* changes other than the changelog"

[Bryce Harrington (bryce)]

LGTM as well, it's almost entirely documentation changes. I skimmed through the actual code changes in the upstream patch and didn't spot anything obviously erroneous.

[Christian Ehrhardt  (paelzer)]

All tests are green OR known force-badtests.
This should be ready for an upload unless Upstream changes the release before it becomes official.

git ubuntu tag pushed in prep for the upload by security

+    The choice of how to partition a table should be made carefully as the

+   </para>
+
+   <para>
+    One of the most critical design decisions will be the column or columns
+    by which you partition your data.  Often the best choice will be to
+    partition by the column or set of columns which most commonly appear in
+    <literal>WHERE</literal> clauses of queries being executed on the
+    partitioned table.  <literal>WHERE</literal> clause items that match and
+    are compatible with the partition key can be used to prune unneeded
+    partitions.  Removal of unwanted data is also a factor to consider when
+    planning your partitioning strategy.  An entire partition can be detached
+    fairly quickly, so it may be beneficial to design the partition strategy
+    in such a way that all data to be removed at once is located in a single
+    partition.
+   </para>
+
+   <para>
+    Choosing the target number of partitions that the table should be divided
+    into is also a critical decision to make.  Not having enough partitions
+    may mean that indexes remain too large and that data locality remains poor
+    which could result in low cache hit ratios.  However, dividing the table
+    into too many partitions can also cause issues.  Too many partitions can
+    mean longer query planning times and higher memory consumption during both
+    query planning and execution.  When choosing how to partition your table,
+    it's also important to consider what changes may occur in the future.  For
+    example, if you choose to have one partition per customer and you
+    currently have a small number of large customers, consider the
+    implications if in several years you instead find yourself with a large
+    number of small customers.  In this case, it may be better to choose to
+    partition by <literal>RANGE</literal> and choose a reasonable number of
+    partitions, each containing a fixed number of customers, rather than
+    trying to partition by <literal>LIST</literal> and hoping that the number
+    of customers does not increase beyond what it is practical to partition
+    the data by.
+   </para>
+
+   <para>
+    Sub-partitioning can be useful to further divide partitions that are
+    expected to become larger than other partitions, although excessive
+    sub-partitioning can easily lead to large numbers of partitions and can
+    cause the same problems mentioned in the preceding paragraph.
+   </para>
+
+   <para>
+    It is also important to consider the overhead of partitioning during
+    query planning and execution.  The query planner is generally able to
+    handle partition hierarchies with up to a few hundred partitions.
+    Planning times become longer and memory consumption becomes higher as more
+    partitions are added.  This is particularly true for the
+    <command>UPDATE</command> and <command>DELETE</command> commands.  Another
+    reason to be concerned about having a large number of partitions is that
+    the server's memory consumption may grow significantly over a period of
+    time, especially if many sessions touch large numbers of partitions.
+    That's because each partition requires its metadata to be loaded into the
+    local memory of each session that touches it.
+   </para>
+
+   <para>
+    With data warehouse type workloads, it can make sense to use a larger
+    number of partitions than with an <acronym>OLTP</acronym> type workload.
+    Generally, in data warehouses, query planning time is less of a concern as
+    the majority of processing time is spent during query execution.  With
+    either of these two types of workload, it is important to make the right
+    decisions early, as re-partitioning large quantities of data can be
+    painfully slow.  Simulations of the intended workload are often beneficial
+    for optimizing the partitioning strategy.  Never assume that more
+    partitions are better than fewer partitions and vice-versa.
