Understand the default configuration

The default configuration consists of:

• A database cluster or directory under which all data will be stored. Depending on your installation type, the default data directory in Bitnami is located at the following paths:

  • Approach A (Bitnami installations using system packages): /bitnami/postgresql/data.
  • Approach B (Self-contained Bitnami installations): /opt/bitnami/postgresql/data.

• Every connection to the PostgreSQL database server is made using the name of some particular role. A database superuser bypasses all permission checks, except the right to log in. Bitnami configures a default superuser role with a name of postgres. The postgres role has remote access to the database.

PostgreSQL version

To obtain the PostgreSQL version, execute the following command:

$ postgres --version

PostgreSQL configuration files

Depending on your installation type, the PostgreSQL configuration files will be located in the following paths:

• Approach A (Bitnami installations using system packages):

  • PostgreSQL configuration settings file: /opt/bitnami/postgresql/conf/pg_hba.conf
  • PostgreSQL client authentication configuration file: /opt/bitnami/postgresql/conf/pg_hba.conf.

• Approach B (Self-contained Bitnami installations):

  • PostgreSQL configuration settings file: /opt/bitnami/postgresql/data/pg_hba.conf
  • PostgreSQL client authentication configuration file: /opt/bitnami/postgresql/data/pg_hba.conf.

The PostgreSQL official documentation has more details on how to configure the PostgreSQL database.

PostgreSQL port

The default port in which PostgreSQL listens is 5432.

PostgreSQL log file

The main PostgreSQL log file is created at /opt/bitnami/postgresql/postgresql.log file. You can change the default error reporting and logging configuration settings in the postgresql.conf file.
