Re: Encryption of .pgpass

Dear Bruce san.

I may be quite persistent.:-)
I seasoned the proposal method. It was very painful that the
conventional connection method to this password was a plain text.
Although I am simple, I desire the support. Furthermore, the relation
between a field item and an environment variable is complicated.

ex.)
inetrt% pqpasswd -U postgres -d postgres
New Password:
Retype New Password:
Succeeded in creation.
inetrt% pqpasswd -U postgres -d postgres -l
/home/saito/.pgpass
hostname=localhost port=5432 dbname=postgres username=postgres password=**********
This 1th line is used.
inetrt% cat /home/saito/.pgpass
localhost:5432:postgres:postgres:postgres
inetrt% psql postgres postgres

I tried correspondence by sufix of md5 to .pgpass, in order to maintain compatibility.
I wish that it is fully reviewed. Thanks.

What is the point of this? It seems to be complicating life to little
purpose (except storing passwords that will fail in non-MD5 password
methods --- given that people are talking about replacing MD5, that
doesn't seem like a good forward-looking idea).

Ahh, yes. It is "crypt" ,"ident" and "pam"...
I do not think that "passwd" should be used primarily.
Then, So, it is clear sufix of md5. It may be a narrower use.
However, I have simplified that it can use as a method of
hiding it. It is suggestion. Is it accepted by including "crypt"?

Thanks.
