Bug reference: 1446
Logged by: John Anson
Email address: postgres (AT) jomich (DOT) com
PostgreSQL version: 8.0.0.5017
Operating system: Windows XP SP2
Description: MSI installion fails if the postgres database password
contains an apostrophe
Details:

The Windows installer fails if the postgres database password contains an
apostrophe.

When I used the password "post'gres" or "post'gres'", the installation
failed with: PostgreSQL 8.0 -- Failed to run initdb: 1!
(I've included the text from initdb.log below).

When I used the password "''''", the installation failed with:
- PostgreSQL 8.0 -- Failed to connect to the database. Procedural languages
files are installed, but are not activated in any databases.
- PostgreSQL 8.0 -- missing "=" after "''''" in connection info string

D:\Program Files\PostgreSQL\8.0\tmp\initdb.log:
The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.
