PostgreSQL encryption

[Paula Carboné]

Hi again! I understand, for what I have read in
https://issues.apache.org/jira/browse/GUACAMOLE-1162 that data encryption
using a PostgreSQL database is not currently possible. However, this issue
talks about using vaults to store credentials
https://issues.apache.org/jira/browse/GUACAMOLE-641
Is it working already or you are just developing it? Can this be used with
PostgreSQL?
Thanks!
