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 |
||||
|
||||
