3 : * initdb --- initialize a PostgreSQL installation
4 : *
5 : * initdb creates (initializes) a PostgreSQL database cluster (site,
6 : * instance, installation, whatever). A database cluster is a
7 : * collection of PostgreSQL databases all managed by the same server.
8 : *
9 : * To create the database cluster, we create the directory that contains
10 : * all its data, create the files that hold the global tables, create
11 : * a few other control files for it, and create three databases: the
12 : * template databases "template0" and "template1", and a default user
13 : * database "postgres".
14 : *
15 : * The template databases are ordinary PostgreSQL databases. template0
16 : * is never supposed to change after initdb, whereas template1 can be
17 : * changed to add site-local standard data. Either one can be copied
18 : * to produce a new database.
19 : *
20 : * For largely-historical reasons, the template1 database is the one built
21 : * by the basic bootstrap process. After it is complete, template0 and
22 : * the default database, postgres, are made just by copying template1.
23 : *
24 : * To create template1, we run the postgres (backend) program in bootstrap
25 : * mode and feed it data from the postgres.bki library file. After this
26 : * initial bootstrap phase, some additional stuff is created by normal
27 : * SQL commands fed to a standalone backend. Some of those commands are
28 : * just embedded into this program (yeah, it's ugly), but larger chunks
29 : * are taken from script files.
30 : *
31 : *
32 : * Note:
33 : * The program has some memory leakage - it isn't worth cleaning it up.
34 : *
35 : * This is a C implementation of the previous shell script for setting up a
36 : * PostgreSQL cluster location, and should be highly compatible with it.
