-Here is a new migratoin file for 1.02.1. It includes the 'copy' change
-and a script to convert old ascii files.
-
----------------------------------------------------------------------------
-
-The following notes are for the benefit of users who want to migrate
-databases from postgres95 1.01 and 1.02 to postgres95 1.02.1.
-
-If you are starting afresh with postgres95 1.02.1 and do not need
-to migrate old databases, you do not need to read any further.
-
-----------------------------------------------------------------------
-
-In order to upgrade older postgres95 version 1.01 or 1.02 databases to
-version 1.02.1, the following steps are required:
-
-1) start up a new 1.02.1 postmaster
-
-2) Add the new built-in functions and operators of 1.02.1 to 1.01 or 1.02
- databases. This is done by running the new 1.02.1 server against
- your own 1.01 or 1.02 database and applying the queries attached at
- the end of thie file. This can be done easily through psql. If your
- 1.01 or 1.02 database is named "testdb" and you have cut the commands
- from the end of this file and saved them in addfunc.sql:
-
- % psql testdb -f addfunc.sql
-
-Those upgrading 1.02 databases will get a warning when executing the
-last two statements because they are already present in 1.02. This is
-not a cause for concern.
-

-
-If you are trying to reload a pg_dump or text-mode 'copy tablename to
-stdout' generated with a previous version, you will need to run the
-attached sed script on the ASCII file before loading it into the
-database. The old format used '.' as end-of-data, while '\.' is now the
-end-of-data marker. Also, empty strings are now loaded in as '' rather
-than NULL. See the copy manual page for full details.
-
- sed 's/^\.$/\\./g' <in_file >out_file
-
-If you are loading an older binary copy or non-stdout copy, there is no
-end-of-data character, and hence no conversion necessary.

-The following notes are for the benefit of users who want to migrate
-databases from postgres95 1.0 to postgres95 1.01.
-
-If you are starting afresh with postgres95 1.01 and do not need
-to migrate old databases, you do not need to read any further.
-
-----------------------------------------------------------------------
-
-In order to postgres95 version 1.01 with databases created with
-postgres95 version 1.0, the following steps are required:
-
-1) Set the definition of NAMEDATALEN in src/Makefile.global to 16
- and OIDNAMELEN to 20.
-
-2) Decide whether you want to use Host based authentication.
-
- A) If you do, you must create a file name "pg_hba" in your top-level data
- directory (typically the value of your $PGDATA). src/libpq/pg_hba
- shows an example syntax.
-
- B) If you do not want host-based authentication, you can comment out
- the line
- HBA = 1
- in src/Makefile.global
-
- Note that host-based authentication is turned on by default, and if
- you do not take steps A or B above, the out-of-the-box 1.01 will
- not allow you to connect to 1.0 databases.
-
-3) compile and install 1.01, but DO NOT do the initdb step.
-
-4) before doing anything else, terminate your 1.0 postmaster, and
- backup your existing $PGDATA directory.
-
-5) set your PGDATA environment variable to your 1.0 databases, but set up
- path up so that 1.01 binaries are being used.
-
-6) modify the file $PGDATA/PG_VERSION from 5.0 to 5.1
-
-7) start up a new 1.01 postmaster
-
-5) Add the new built-in functions and operators of 1.01 to 1.0
- databases. This is done by running the new 1.01 server against
- your own 1.0 database and applying the queries attached and saving
- in the file 1.0_to_1.01.sql. This can be done easily through psql.
- If your 1.0 database is name "testdb":
-
- % psql testdb -f 1.0_to_1.01.sql
-
