Building a PostgreSQL cluster involves going through the following steps:

Install the PostgreSQL software: First, you will need to install the PostgreSQL database software on all cluster nodes.
Configure PostgreSQL instances: on each node, configure the configuration file of PostgreSQL instances, including database name, listening address, port, and other information.
Configure communication between cluster nodes: Ensure that cluster nodes can communicate with each other, using methods such as SSH or SSL to ensure secure communication.
Set up master-slave replication by designating one node as the master node and the rest as slave nodes, ensuring data synchronization.
Set up load balancing: You can use software like HAProxy or pgpool to ensure that requests are evenly distributed to each node.
Test Cluster: After completion of the setup, it is necessary to conduct testing, including failover and data synchronization to ensure the normal operation of the cluster.
Monitoring and maintenance: Regularly monitor the operation of clusters, including performance, availability, and other metrics, and promptly conduct maintenance and troubleshooting when necessary.
