Multiple postgres processes on Linux NetBackup servers
Some users may notice that with the new NetBackup database in 10.2, a number of instances of postgres
run on the NetBackup server. One instance is the primary server process that runs the database cluster. It is the first process started and performs recovery operations, initializes shared memory, and runs background processes.
PostgreSQL also spawns additional processes when there is a connection request from a client process. (For more information, see the PostgreSQL documentation: https://www.postgresql.org/docs/current/app-postgres.html.) Each background instance is dedicated to specific purpose. For example: automatic database maintenance, logging error messages, updating and collecting statistics, and handling the client connection from the various programs that want to perform database activities.
