-- @formatter:off because of terribly unreliable IDEA reformat for SQL
-- Naming conventions:
-- M_ prefix is used for tables in main part of the repo, MA_ for audit tables (can be separate)
-- Constraints/indexes use table_column(s)_suffix convention, with PK for primary key,
-- FK foreign key, IDX for index, KEY for unique index.
-- TR is suffix for triggers.
-- Names are generally lowercase (despite prefix/suffixes above in uppercase ;-)).
-- Column names are Java style and match attribute names from M-classes (e.g. MObject).
--
-- Other notes:
-- TEXT is used instead of VARCHAR, see: https://dba.stackexchange.com/a/21496/157622
-- We prefer "CREATE UNIQUE INDEX" to "ALTER TABLE ... ADD CONSTRAINT", unless the column
-- is marked as UNIQUE directly - then the index is implied, don't create it explicitly.
--
-- For Audit tables see 'postgres-new-audit.sql' right next to this file.
-- For Quartz tables see 'postgres-new-quartz.sql'.

-- region Schema versioning and upgrading
/*
Procedure applying a DB schema/data change for main repository tables (audit has separate procedure).
Use sequential change numbers to identify the changes.
This protects re-execution of the same change on the same database instance.
Use dollar-quoted string constant for a change, examples are lower, docs here:
https://www.postgresql.org/docs/current/sql-syntax-lexical.html#SQL-SYNTAX-DOLLAR-QUOTING
The transaction is committed if the change is executed.
The change number is NOT semantic and uses different key than original 'databaseSchemaVersion'.
Semantic schema versioning is still possible, but now only for information purposes.

Example of an DB upgrade script (stuff between $$ can be multiline, here compressed for brevity):
CALL apply_change(1, $$ create table x(a int); insert into x values (1); $$);
CALL apply_change(2, $$ alter table x add column b text; insert into x values (2, 'two'); $$);
-- not a good idea in general, but "true" forces the execution; it never updates change # to lower
CALL apply_change(1, $$ insert into x values (3, 'three'); $$, true);
*/

    LANGUAGE plpgsql
