+PG_UPGRADE: IN-PLACE UPGRADES FOR POSTGRESQL
+------------------------------------------------------------------------------
+
+Upgrading a PostgreSQL database from one major release to another can be
+an expensive process. For minor upgrades, you can simply install new
+executables and forget about upgrading existing data. But for major
+upgrades, you have to export all of your data using pg_dump, install the
+new release, run initdb to create a new cluster, and then import your
+old data. If you have a lot of data, that can take a considerable amount
+of time. If you have too much data, you may have to buy more storage
+since you need enough room to hold the original data plus the exported
+data.  pg_upgrade can reduce the amount of time and disk space required
+for many upgrades.
+
+The URL http://momjian.us/main/writings/pgsql/pg_upgrade.pdf contains a
+presentation about pg_upgrade internals that mirrors the text
+description below.
+
+------------------------------------------------------------------------------
+WHAT IT DOES
+------------------------------------------------------------------------------
+
+pg_upgrade is a tool that performs an in-place upgrade of existing
+data. Some upgrades change the on-disk representation of data;
+pg_upgrade cannot help in those upgrades.  However, many upgrades do
+not change the on-disk representation of a user-defined table.  In those
+cases, pg_upgrade can move existing user-defined tables from the old
+database cluster into the new cluster.
+
+There are two factors that determine whether an in-place upgrade is
+practical.
+
+Every table in a cluster shares the same on-disk representation of the
+table headers and trailers and the on-disk representation of tuple
+headers. If this changes between the old version of PostgreSQL and the
+new version, pg_upgrade cannot move existing tables to the new cluster;
+you will have to pg_dump the old data and then import that data into the
+new cluster.
+
+Second, all data types should have the same binary representation
+between the two major PostgreSQL versions.
+
+------------------------------------------------------------------------------
+HOW IT WORKS
+------------------------------------------------------------------------------
+
+To use pg_upgrade during an upgrade, start by installing a fresh
+cluster using the newest version in a new directory. When you've
+finished installation, the new cluster will contain the new executables
+and the usual template0, template1, and postgres, but no user-defined
+tables. At this point, you can shut down the old and new postmasters and
+invoke pg_upgrade.
+
+When pg_upgrade starts, it ensures that all required executables are
+present and contain the expected version numbers. The verification
+process also checks the old and new $PGDATA directories to ensure that
+the expected files and subdirectories are in place.  If the verification
+process succeeds, pg_upgrade starts the old postmaster and runs
+pg_dumpall --schema-only to capture the metadata contained in the old
+cluster. The script produced by pg_dumpall will be used in a later step
+to recreate all user-defined objects in the new cluster.
+
+Note that the script produced by pg_dumpall will only recreate
+user-defined objects, not system-defined objects.  The new cluster will
+contain the system-defined objects created by the latest version of
+PostgreSQL.
+
+Once pg_upgrade has extracted the metadata from the old cluster, it
+performs a number of bookkeeping tasks required to 'sync up' the new
+cluster with the existing data.
+
+First, pg_upgrade copies the commit status information and 'next
+transaction ID' from the old cluster to the new cluster. This step
+ensures that the proper tuples are visible from the new cluster.
+Remember, pg_upgrade does not export/import the content of user-defined
+tables so the transaction IDs in the new cluster must match the
+transaction IDs in the old data. pg_upgrade also copies the starting
+address for write-ahead logs from the old cluster to the new cluster.
+
+Now pg_upgrade begins reconstructing the metadata obtained from the old
+cluster using the first part of the pg_dumpall output.
+
+Next, pg_upgrade executes the remainder of the script produced earlier
+by pg_dumpall --- this script effectively creates the complete
+user-defined metadata from the old cluster to the new cluster.  It
+preserves the relfilenode numbers so TOAST and other references
+to relfilenodes in user data is preserved.  (See binary-upgrade usage
+in pg_dump).
+
+Finally, pg_upgrade links or copies each user-defined table and its
+supporting indexes and toast tables from the old cluster to the new
+cluster.
+
+An important feature of the pg_upgrade design is that it leaves the
+original cluster intact --- if a problem occurs during the upgrade, you
+can still run the previous version, after renaming the tablespaces back
+to the original names.

+THE SHORT VERSION
+-----------------
+
+On non-Windows machines, you can execute the testing process
+described below by running
+	make check
+in this directory.  This will run the shell script test.sh, performing
+an upgrade from the version in this source tree to a new instance of
+the same version.
+
+To test an upgrade from a different version, you must have a built
+source tree for the old version as well as this version, and you
+must have done "make install" for both versions.  Then do:
+
+export oldsrc=...somewhere/postgresql	(old version's source tree)
+export oldbindir=...otherversion/bin	(old version's installed bin dir)
+export bindir=...thisversion/bin	(this version's installed bin dir)
+export libdir=...thisversion/lib	(this version's installed lib dir)
+sh test.sh
+
+In this case, you will have to manually eyeball the resulting dump
+diff for version-specific differences, as explained below.
+
+
+DETAILS
+-------
+
+The most effective way to test pg_upgrade, aside from testing on user
+data, is by upgrading the PostgreSQL regression database.
+
+This testing process first requires the creation of a valid regression
+database dump.  Such files contain most database features and are
+specific to each major version of Postgres.
+
+Here are the steps needed to create a regression database dump file:
+
+1)  Create and populate the regression database in the old cluster.
+    This database can be created by running 'make installcheck' from
+    src/test/regress.
+
+2)  Use pg_dump to dump out the regression database.  Use the new
+    cluster's pg_dump on the old database to minimize whitespace
+    differences in the diff.
+
+3)  Adjust the regression database dump file
+
+    a)  Perform the load/dump twice
+        This fixes problems with the ordering of COPY columns for
+        inherited tables.
+
+    b)  Change CREATE FUNCTION shared object paths to use '$libdir'
+        The old and new cluster will have different shared object paths.
+
+    c)  Fix any wrapping format differences
+        Commands like CREATE TRIGGER and ALTER TABLE sometimes have
+        differences.
+
+    d)  For pre-9.0, change CREATE OR REPLACE LANGUAGE to CREATE LANGUAGE
+
+    e)  For pre-9.0, remove 'regex_flavor'
+
+    f)  For pre-9.0, adjust extra_float_digits
+        Postgres 9.0 pg_dump uses extra_float_digits=-2 for pre-9.0
+        databases, and extra_float_digits=-3 for >= 9.0 databases.
+        It is necessary to modify 9.0 pg_dump to always use -3, and
+        modify the pre-9.0 old server to accept extra_float_digits=-3.
+
+Once the dump is created, it can be repeatedly loaded into the old
+database, upgraded, and dumped out of the new database, and then
+compared to the original version. To test the dump file, perform these
+steps:
+
+1)  Create the old and new clusters in different directories.
+
+2)  Copy the regression shared object files into the appropriate /lib
+    directory for old and new clusters.
+
+3)  Create the regression database in the old server.
+
+4)  Load the dump file created above into the regression database;
+    check for errors while loading.
+
+5)  Upgrade the old database to the new major version, as outlined in
+    the pg_upgrade manual section.
+
+6)  Use pg_dump to dump out the regression database in the new cluster.
+
+7)  Diff the regression database dump file with the regression dump
+    file loaded into the old server.
