Adrian, David,

Thank you so much for the quick response.

What would be the point of storing the encrypted password instead of the plaintext one? As per our organization security policies, we can 't keep any  passwords in plain text format.

But if you want to log in with encrypted password and someone can grab it from the file not sure what the difference is from grabbing the plain text one if they both end up logging the user in?



I am working on postgres + pgbouncer setup, tested pgbouncer 1.14 where we have support to use encrypted password in userlist,txt file. I am surprised why  pgpass is not supporting encrypted passwords.

        I am using below format and it is not working for me

        /|pglnx1|/:/|5432|/:pgbouncer:/|pgadmin|/:"SCRAM-SHA-256$4096:6IDsjfedwsdpymp0Za7jaMew==$rzSoYL4ZYsW1WJAj7Lt3JtNLNR73AVY7sfsauikweblk][=:Hxx/juPXJZHy5djPctI=*/"/*

    The documentation doesn't say so one way or the other so I would go
    with no.  The password in the pgpass file has to be the plaintext
    password.  The client, upon speaking with the server, will decide
    whether to send the plaintext password to the server or encrypt it
    prior to transmission.

    What would be the point of storing the encrypted password instead of
    the plaintext one?
