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.
