CREATE EXTENSION requires SUPERUSER (Postgres < 13) or CREATE privileges (Postgres >= 13).
Either configure a migration user with sufficient privileges via database.migration.username
and database.migration.password, or create the extension manually. The below statement will
not fail if the extension already exists, even though the user might now have sufficient
privileges to create it.

Create a GIN index to support LIKE '%foo%' queries for dependency graph traversal.
Creating this index on an existing database might take a while, so do it concurrently
to not block writes on the "COMPONENT" table. Index creation cannot run in a transaction
