BEGIN;

-- IMPORTANT(fusion): PosgreSQL doesn't have a defined `NOCASE` collation like

-- SQLite and doesn't use a default case-insensitive collation like MySQL. The

-- simplest alternative is to create a custom non-deterministic ICU collation.

-- ICU as a collation provider is supported with PostgreSQL 10+, while

-- non-deterministic collations are supported with PostgreSQL 12+. Either way,

-- it should be safe to assume that it's widely supported, given that version

-- 12 is roughly 6 years old and well past its end-of-life.

-- There are also drawbacks from using these types of collations but I won't

-- go into details. For more information see:

-- https://www.postgresql.org/docs/current/collation.html

CREATE COLLATION NOCASE (

provider = icu,

deterministic = false,

locale = 'und-u-ks-level2'

);

-- IMPORTANT(fusion): Since we're already assuming PostgreSQL 12+ for collations,

-- it's probably a good idea to use IDENTITY columns instead of SERIAL. They're

-- supported with PostgreSQL 10+ and are supposed so fix some shortcommings of

-- SERIAL.

-- TODO(fusion): SQLite tables didn't use foreign key constraints so I'm also not

-- using them here. It might be a good idea for consistency, but it's not a hard

-- requirement.

-- NOTE(fusion): A table with schema information. It currently only contains the

-- schema version which is checked at startup against `POSTGRESQL_SCHEMA_VERSION`,

-- defined in `database_postgres.cc`. The query manager will only startup if the

-- versions match.
