|
* initdb --- initialize a PostgreSQL installation
|
|
*
|
|
* 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 server.
|
|
*
|
|
* 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 three databases: the
|
|
* template databases "template0" and "template1", and a default user
|
|
* database "postgres".
|
|
*
|
|
* 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.
|
|
*
|
|
* For largely-historical reasons, the template1 database is the one built
|
|
* by the basic bootstrap process. After it is complete, template0 and
|
|
* the default database, postgres, are made just by copying template1.
|
|
*
|
|
* 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. Some of those commands are
|
|
* just embedded into this program (yeah, it's ugly), but larger chunks
|
|
* are taken from script files.
|
|
*
|
|
*
|
|
* Note:
|
|
* The program has some memory leakage - it isn't worth cleaning it up.
|
|
*
|
|
* This is a C implementation of the previous shell script for setting up a
|
|
* PostgreSQL cluster location, and should be highly compatible with it.
