Bug#861689: PostgreSQL PL/Perl incompatibility

[Christoph Berg <myon@debian.org>]

Package: release-notes
Severity: normal
Tags: patch

Hi,

for hopefully the last time, we need to document the postgresql-plperl
upgrade process. (For stretch/buster+, the libperl* packages should be
co-installable.)

+      The PostgreSQL PL/Perl procedural language package in jessie is
+      incompatible with the Perl version in stretch. The
+      <systemitem role="package">postgresql-plperl-9.4</systemitem> package
+      will be removed during the update, rendering server-side Perl procedures
+      dysfunctional. Upgrading to PostgreSQL 9.6 should be unaffected, the
+      procedures will work in the new PostgreSQL cluster if the
+      <systemitem role="package">postgresql-plperl-9.6</systemitem> package
+      is installed. If unsure, take a backup of your PostgreSQL 9.4 clusters
+      before upgrading to stretch.
