-#-------------------------------------------------------------------------
-#
-# initdb creates (initializes) a PostgreSQL database cluster (site,
-# instance, installation, whatever).  A database cluster is a
-# collection of PostgreSQL databases all managed by the same postmaster.
-#
-# To create the database cluster, we create the directory that contains
-# all its data, create the files that hold the global tables, create
-# a few other control files for it, and create two databases: the
-# template0 and template1 databases.
-#
-# The template databases are ordinary PostgreSQL databases.  template0
-# is never supposed to change after initdb, whereas template1 can be
-# changed to add site-local standard data.  Either one can be copied
-# to produce a new database.
-#
-# To create template1, we run the postgres (backend) program in bootstrap
-# mode and feed it data from the postgres.bki library file.  After this
-# initial bootstrap phase, some additional stuff is created by normal
-# SQL commands fed to a standalone backend.  Those commands are just
-# embedded into this script (yeah, it's ugly).
-#
-# template0 is made just by copying the completed template1.
