Issue/Introduction
APM requires an external database (either Postgres or Oracle) for holding Team Center and CEM data structures. This article explains how to change passwords associated with the APM Database in Postgres after installation.
What command should I use to update the password of my APM database user?
Environment
DX APM 10.x releases with Postgres installed.
Resolution
Passwords for the APM database on Postgres can be altered either via the command line or PGAdmin by doing the following:
a) On Windows:
click Start -> Program -> Windows -> PostgresSQL<version> -> PSQL and type Postgres then enter the password of the PostgresSQL Administrator .
b) On Linux enter:
psql -U username -d databasename
Then enter the password of the PostgresSQL Administrator. To change the password of any APM Database User, type:
ALTER ROLE <user> WITH PASSWORD 'newpassword';
For more information regarding the ALTER ROLE command, refer to the Postgresql documentation.
https://www.postgresql.org/docs/13/sql-alterrole.html
In addition, you can use the ALTER USER command, which is an alias for ALTER ROLE:

Additional Information
If you change the password for the APM Database User, not to be confused with the Postgresql Administrative User, this information will also need to be updated on each of the Enterprise Managers. To do this:
1) open <EM Home>\config\ tess-db-cfg.xml
2) update the hibernate.connection.password with the new password, in plain text.
Also set plainTextPasswords to true, so that the EM password is encrypted on EM restart, and then restart the EM.
From tess-db-config.xml:
<property name="hibernate.connection.password">MyNewPassword</property>
<property name="plainTextPasswords">true</property>
