|

# Create (initialize) a Postgres database system.
|
||||
#
|
||||
# A database system is a collection of Postgres databases all managed
|
||||
# by the same postmaster.
|
||||
#
|
||||
# To create the database system, we create the directory that contains
|
||||
# all its data, create the files that hold the global classes, create
|
||||
# a few other control files for it, and create one database: the
|
||||
# template database.
|
||||
#
|
||||
# The template database is an ordinary Postgres database. Its data
|
||||
# never changes, though. It exists to make it easy for Postgres to
|
||||
# create other databases -- it just copies.
|
||||
#
|
||||
# Optionally, we can skip creating the database system and just create
|
||||
# (or replace) the template database.
|
||||
#
|
||||
# To create all those classes, we run the postgres (backend) program and
|
||||
# feed it data from bki files that are in the Postgres library directory.
