PG_PWD and PG_PASSWORD Security

Hi,

When I 'CREATE USER testuser WITH PASSWORD 'mypassword';

I see an entry in PG_PWD with the password 'mypassword' in plaintext.

In my pg_hba.conf I have all hosts using 'password' authentication with no

file argument. Is there any way to keep postgres from saving the passwords

in plain text? This seems to be a huge security hole. I thought that passwords were to be saved in PG_SHADOW. What is

PG_SHADOW for anyway?

If you have an answer, can you please cc: my email?

Thanks.
