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.
