+-- NOTE(fusion): Everything is inside a transaction to avoid errors from leaving

+-- 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 collation.
+--  This is only supported with PostgreSQL 10+ but it should safe to assume that
+-- it's widely supported, given that it's almost 10 years old and well past its
+-- end-of-life.

+-- IMPORTANT(fusion): Since we're already assuming PostgreSQL 10+ for collations,
+-- it's probably a good idea to use IDENTITY columns instead of SERIAL. They're
+-- also 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
