|
# 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.
