I installed PosgreSQL 12 using the certified installer by EnterpriseDB.
I went through the docs. In Chapter 18.2. Creating a Database Cluster, it is said that you need to initialize a database cluster with the command
initdb, for example:
$ initdb -D /usr/local/pgsql/data.
Do I actually need to initialize a database cluster? The documentation says that the databases
template1 are created within each cluster during initialization. When I start the database server using pgAdmin 4 I see these databases there. I assume that I need to do it manually when I install PostgreSQL from source code, otherwise it is done automatically during instalation. Right?
