--- # 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 literally nothing (0 rows).
--- >> RETURNS VOID<< IS similar, but it still outputs "empty line" in psql when calling.
