Merge ~athos-ribeiro/ubuntu/+source/postgresql-10:MRE-bionic-10.20 into ubuntu/+source/postgresql-10:ubuntu/bionic-devel

[Athos Ribeiro]

MRE of postgresql-10 10.20 for bionic.

As discussed in LP: #1961127, autopkgtest.u.c is currently under heavy load. Hence, we decided to upload to bionic-proposed directly and deal with the official autopkgtest results there.

-# SYNOPSIS
-#
-#   AX_PROG_PERL_MODULES([MODULES], [ACTION-IF-TRUE], [ACTION-IF-FALSE])
-#
-# DESCRIPTION
-#
-#   Checks to see if the given perl modules are available. If true the shell
-#   commands in ACTION-IF-TRUE are executed. If not the shell commands in
-#   ACTION-IF-FALSE are run. Note if $PERL is not set (for example by
-#   calling AC_CHECK_PROG, or AC_PATH_PROG), AC_CHECK_PROG(PERL, perl, perl)
-#   will be run.
-#
-#   MODULES is a space separated list of module names. To check for a
-#   minimum version of a module, append the version number to the module
-#   name, separated by an equals sign.
-#
-#   Example:
-#
-#     AX_PROG_PERL_MODULES( Text::Wrap Net::LDAP=1.0.3, ,
-#                           AC_MSG_WARN(Need some Perl modules)

+    To avoid blocking concurrent transactions that obtain numbers from
+    the same sequence, the value obtained by <function>nextval</function>
+    is not reclaimed for re-use if the calling transaction later aborts.
+    This means that transaction aborts or database crashes can result in
+    gaps in the sequence of assigned values.  That can happen without a
+    transaction abort, too.  For example an <command>INSERT</command> with
+    an <literal>ON CONFLICT</literal> clause will compute the to-be-inserted

+    Likewise, sequence state changes made by <function>setval</function>

+   </para>
+
+   <para>
+    If the database cluster crashes before committing a transaction
+    containing a <function>nextval</function>
+    or <function>setval</function> call, the sequence state change might
+    not have made its way to persistent storage, so that it is uncertain
+    whether the sequence will have its original or updated state after the
+    cluster restarts.  This is harmless for usage of the sequence within
+    the database, since other effects of uncommitted transactions will not
+    be visible either.  However, if you wish to use a sequence value for
+    persistent outside-the-database purposes, make sure that the
