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
------------------------------------------------------------------------------
-- add builtin functions that are new to 1.01 -- add builtin functions that are new to 1.01
create function int4eqoid (int4, oid) returns bool as 'foo' create function int4eqoid (int4, oid) returns bool as 'foo'
