E.210. Release 1.01

Set the definition of NAMEDATALEN in src/Makefile.global to 16 and OIDNAMELEN to 20.

Decide whether you want to use Host based authentication.

1. 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.

2. 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.

Compile and install 1.01, but DO NOT do the initdb step.

Before doing anything else, terminate your 1.0 postmaster, and backup your existing $PGDATA directory.

Set your PGDATA environment variable to your 1.0 databases, but set up path up so that 1.01 binaries are being used.

Modify the file $PGDATA/PG_VERSION from 5.0 to 5.1

Start up a new 1.01 postmaster

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

and then execute the following commands (cut and paste from here):
