+# print a list of PostgreSQL versions that are supported for the platform this
+# script runs on.
+# Note: Newer installed versions than the highest one listed here are always
+# considered supported, so that backports will not cause an "obsolete" warning.
+#
+# /usr/share/postgresql-common/supported-versions decides which PostgreSQL
+# server versions are supported. This information is used
+# 1) for notifying users of obsolete versions, suggesting to upgrade
+# 2) by postgresql-common itself (in debian/rules) to determine the
+# dependencies of the postgresql meta packages (default version), and to
+# generate the list of postgresql-server-dev-* packages
+# postgresql-server-dev-all depends on
+# 3) by the pg_buildext tool to decide which server versions to build extension
+# modules for
+#
+# The *last* version returned here will be considered the default version, the
+# remaining lines list other supported versions in an undefined order.
+#
+# * PG_SUPPORTED_VERSIONS
+# * DEB_PG_SUPPORTED_VERSIONS
+# * ~/.pg_supported_versions
+# * /etc/postgresql-common/supported_versions
+# (in that order) can be used to override the defaults. (Tokens separated by
+# newlines.)
+#
+# Recognized tokens:
+# default: use the appropiate defaults for the current distribution
+# (as determined by os-release)
+# debian: use Debian defaults
+# debian-backports: use Debian Backports defaults
+# ubuntu: use Ubuntu defaults
+# pgdg: use defaults for apt.postgresql.org
+# installed: consider all installed versions supported (determined by
+# postgresql-server-dev-X packages)
+# X: consider this version supported
