Dear all,

The initdb seems did not escape (PQescapeString) the password. The
following is my test result, with password: ab'ds)24

imacat(at)atlas ~ % initdb -D /tmp/postgres -E utf8 --locale=en_US.utf8 -U postgres -W
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 en_US.utf8.

I have attached a patch that seems to solve this issue. It works
for me. Please tell me if there is any problem.
