Is it possible to install PostgreSQL 10.x or higher with Plesk?

Install the PostgreSQL repository (replace link with the one obtained in previous step):

Disable the built-in PostgreSQL module:

# dnf -qy module disable postgresql

Initialize the database:

# /usr/pgsql-XX/bin/postgresql-XX-setup initdb

Set PostgreSQL to start on boot:

# systemctl enable postgresql-XX

Start PostgreSQL:

# systemctl start postgresql-XX

Create a symlink between installed version and postgresql service:

# ln -s /usr/lib/systemd/system/postgresql-XX.service /usr/lib/systemd/system/postgresql.service

Switch to user postgres:

# su - postgres

Set a password for the user:

# psql -c "ALTER USER postgres WITH PASSWORD 'YourSecurePassword';"
