-- | Drops and recreates all “system-defined” metadata, aka metadata for tables and views in the
-- @information_schema@ and @hdb_catalog@ schemas. These tables and views are tracked to expose them
-- to the console, which allows us to reuse the same functionality we use to implement user-defined
-- APIs to expose the catalog.
--
-- This process has a long and storied history.
--
-- In the past, we reused the same machinery we use for CLI migrations to define our own internal
-- metadata migrations. This caused trouble, however, as we’d have to run those migrations in
-- lockstep with our SQL migrations to ensure the two didn’t get out of sync. This in turn caused
-- trouble because those migrations would hit code paths inside @graphql-engine@ to add or remove
-- things from the @pg_catalog@ tables, and /that/ in turn would fail because we hadn’t finished
-- running the SQL migrations, so we were running a new version of the code against an old version
-- of the schema! That caused #2826.
--
-- To fix that, #2379 switched to the approach of just dropping and recreating all system metadata
-- every time we run any SQL migrations. But /that/ in turn caused trouble due to the way we were
-- constantly rebuilding the schema cache (#3354), causing us to switch to incremental schema cache
-- construction (#3394). However, although that mostly resolved the problem, we still weren’t
-- totally out of the woods, as the incremental construction was still too slow on slow Postgres
-- instances (#3654).
--
-- To sidestep the whole issue, as of #3686 we now just create all the system metadata in code here,
-- and we only rebuild the schema cache once, at the very end. This is a little unsatisfying, since
-- it means our internal migrations are “blessed” compared to user-defined CLI migrations. If we
-- improve CLI migrations further in the future, maybe we can switch back to using that approach,
-- instead.
