password is plaintext while use pg_dist_authinfo

Please give me some help. T_T

I am using citus for building database cluster, one cn and two worker node.
for authentication， I use pg_dist_authinfo:

```
select * from pg_dist_authinfo;
nodeid | rolename | authinfo
--------+-----------+-----------------------
0 | role_1 | password=Test@2022
```
but the password show in plaintext, which is not allow in my server environments；

how can i solve this problem？ Is there a switch to control ciphertext or plaintext while querying pg_dist_authinfo?
or some encryption and decryption solutions ？
or some other authentication solutions can I choose ?

thank you very much!
