+-- # NAME
+--
+-- **Versioning** - simplistic take on tracking and applying changes to databases.
+--
+-- # DESCRIPTION
+--
+-- This project strives to provide simple way to manage changes to
+-- database.
+--
+-- Instead of making changes on development server, then finding
+-- differences between production and development, deciding which ones
+-- should be installed on production, and finding a way to install them -
+-- you start with writing diffs themselves!
+--
+-- # INSTALLATION
+--
+-- To install versioning simply run install.versioning.sql in your database
+-- (all of them: production, stage, test, devel, ...).
+--
+-- # USAGE
+--
+-- In your files with patches to database, put whole logic in single
+-- transaction, and use \_v.\* functions - usually \_v.register_patch() at
+-- least to make sure everything is OK.
+--
+-- For example. Let's assume you have patch files:
+--
+-- ## 0001.sql:
+--
+-- ```
+-- create table users (id serial primary key, username text);
+-- ```
+--
+-- ## 0002.sql:
+--
+-- ```
+-- insert into users (username) values ('depesz');
+-- ```
+-- To change it to use versioning you would change the files, to this
+-- state:
+--
+-- 0000.sql:
+--
+-- ```
+-- BEGIN;
+-- select _v.register_patch('000-base', NULL, NULL);
+-- create table users (id serial primary key, username text);
+-- COMMIT;
+-- ```
+--
+-- ## 0002.sql:
+--
+-- ```
+-- BEGIN;
+-- select _v.register_patch('001-users', ARRAY['000-base'], NULL);
+-- insert into users (username) values ('depesz');
+-- COMMIT;
+-- ```
+--
+-- This will make sure that patch 001-users can only be applied after
+-- 000-base.
+--
+-- # AVAILABLE FUNCTIONS
+--
+-- ## \_v.register_patch( TEXT )
+--
+-- Registers named patch, or dies if it is already registered.
+--
+-- Returns integer which is id of patch in \_v.patches table - only if it
+-- succeeded.
+--
+-- ## \_v.register_patch( TEXT, TEXT[] )
+--
+-- Same as \_v.register_patch( TEXT ), but checks is all given patches (given as
+-- array in second argument) are already registered.
+--
+-- ## \_v.register_patch( TEXT, TEXT[], TEXT[] )
+--
+-- Same as \_v.register_patch( TEXT, TEXT[] ), but also checks if there are no conflicts with preexisting patches.
+--
+-- Third argument is array of names of patches that conflict with current one. So
+-- if any of them is installed - register_patch will error out.
+--
+-- ## \_v.unregister_patch( TEXT )
+--
+-- Removes information about given patch from the versioning data.
+--
+-- It doesn't remove objects that were created by this patch - just removes
+-- metainformation.
+--
+-- ## \_v.assert_user_is_superuser()
+--
+-- Make sure that current patch is being loaded by superuser.
+--
+-- If it's not - it will raise exception, and break transaction.
+--
+-- ## \_v.assert_user_is_not_superuser()
+--
+-- Make sure that current patch is not being loaded by superuser.
+--
+-- If it is - it will raise exception, and break transaction.
+--
+-- ## \_v.assert_user_is_one_of(TEXT, TEXT, ... )
+--
+-- Make sure that current patch is being loaded by one of listed users.
+--
+-- If ```current_user``` is not listed as one of arguments - function will raise
+-- exception and break the transaction.
+
+BEGIN;
+
+-- This file adds versioning support to database it will be loaded to.
+-- It requires that PL/pgSQL is already loaded - will raise exception otherwise.
+-- All versioning "stuff" (tables, functions) is in "_v" schema.
+
+-- All functions are defined as 'RETURNS SETOF INT4' to be able to make them to RETURN literaly nothing (0 rows).
+-- >> RETURNS VOID<< IS similar, but it still outputs "empty line" in psql when calling.
