PostgreSQL 12 in Amazon Linux AMI 2

Question

Hi for all.  
  
PostgreSQL 12 is now available in RDS but in Amazon Linux AMI 2 client is still at 11.2.   
This causes a version mismatch issue for us in pg_dump.  
Anybody has any suggestion or know if is there any forecast to make PostgreSQL 12 available in Amazon Linux AMI 2?  
  
Regards.

Hi Fernando,  
  
Next are the step to install PostgreSQL 12.X on your environment:  
  
1.- Create an EBS snapshot of your system (highly recommended)  
2.- Create a new repo for "PostgreSQL 12 for RHEL/CentOS 7 - x86_64" with the following command:  
  
$ sudo tee /etc/yum.repos.d/pgdg.repo<
