I defined a tsvector column with

search Unsupported("tsvector")?

and then the GIN index in the migration. when I run migrations though it creates a new migration that tries to drop my GIN indexes. the docs say "You can continue using Prisma Migrate as you were before, it will ignore indexes that it doesn't know about." am I missing a step? also I can't search on my tsvector column; it doesn't appear in my generated schema
