# postgresql.service is the meta unit for managing all PostgreSQL clusters on
# the system at once. Conceptually, this unit is more like a systemd target,
# but we are using a service since targets cannot be reloaded.
#
# The unit actually managing PostgreSQL clusters is postgresql@.service,
# instantiated as postgresql@15-main.service for individual clusters.
