-- Convention for database items with version control:
--
--   CREATE TABLE items ( -- dbentry_type=x
--     id        vndbid NOT NULL PRIMARY KEY ..,
--     locked    boolean NOT NULL DEFAULT FALSE,
--     hidden    boolean NOT NULL DEFAULT FALSE,
--     -- item-specific columns here
--   );
--   CREATE TABLE items_hist ( -- History of the 'items' table
--     chid integer NOT NULL,  -- references changes.id
--     -- item-specific columns here
--   );
--
-- The '-- dbentry_type=x' comment is required, and is used by sqleditfunc.pl
-- to generate the correct editing functions. It's possible for 'items' to have
-- more item-specific columns than 'items_hist'.  Some columns are caches or
-- otherwise autogenerated, and do not need to be versioned.
--
-- The (hidden,locked) columns indicate the item's state:
--   !hidden && !locked -> Normal
--   !hidden &&  locked -> Locked
--    hidden && !locked -> Awaiting approval (tags/traits only)
--    hidden &&  locked -> Deleted
-- The history of these flags is recorded as (ihid,ilock) in the changes table.
-- (Yes, the state is better represented as an ENUM, but this way it's easier
-- to filter out 'hidden' items in listings)
--
-- item-related tables work roughly the same:
--
--   CREATE TABLE items_field (
--     id vndbid,  -- references items.id
--     -- field-specific columns here
--   );
--   CREATE TABLE items_field_hist ( -- History of the 'items_field' table
--     chid integer, -- references changes.id
--     -- field-specific columns here
--   );
--
-- The changes and *_hist tables contain all the data. In a sense, the other
-- tables related to the item are just a cache/view into the latest versions.
-- All modifications to the item tables has to go through the edit_* functions
-- in editfunc.sql, these are also responsible for keeping things synchronized.
--
-- Columns marked with a '[pub]' comment on the same line are included in the
-- public database dump. Be aware that not all properties of the to-be-dumped
-- data are annotated in this file. Which tables and which rows are exported is
-- defined in util/dbdump.pl.
--
-- Comments on CREATE TABLE and column lines for '[pub]' items are included in
-- the public database dump import.sql in the form of "COMMENT ON" commands.
--
-- Columns in tables are generally ordered for efficient storage: larger
-- fixed-sized columns go before smaller fixed-sized columns, variable-length
-- columns go at the end. When a new column is added to a table, it should
-- always be added at the end because that's the only thing Postgres supports.
-- Once in a while I re-order all newly added columns for efficiency and that
-- requires a full dump and re-import of the database using
--   util/dbdump.pl export-data
-- to take effect.  That's why I typically plan these at the same time that I'm
-- upgrading to a new major Postgres version, after all, a dump-and-import is a
-- good upgrade strategy.
-- Code should not depend on column order!
--
-- Note: Every CREATE TABLE clause and each column should be on a separate
-- line. This file is parsed by lib/VNDB/Schema.pm and it doesn't implement a
-- full SQL query parser.
