PostgreSQL backup error - missing libpq.so

Hi - we have been backing up RDS postgres exports fine for a long time with version 14

We are upgrading to version 16 but the postgresql agent seems to be missing some library files?

The job error is:

PostgreSQL Database: [~Loading libpq.so library failed. Please check if required libpq.so file exists in Postgres Lib directory~] Data Backup Failed.<br/>Source: aws-cvpxy-lnx-105, Process: PostGresIfind

Looking on our proxy node I can see version 16 & 17 are missing the required file: 

$ find / -name "libpq.so*" 2>/dev/null

The Postgres Agent is deployed on an EC2 host that is rebuilt weekly using the API so it is running the latest version all the time.
