Migration `20211207122745_genesis` failed to apply cleanly to the shadow database. 
db error: ERROR: function uuid_generate_v4() does not exist

And:

postgres=# select uuid_generate_v4();
           uuid_generate_v4

what is meant by "shadow database", is this not my maintenance database? Does the uuid function actually need to be "installed" in each individual database?

Hey Barnaby 👋 the Shadow DB is used by Prisma Migrate to execute a migration, you can read more about it in our docs here.

Does the uuid function actually need to be “installed” in each individual database?

I would believe so, did you try this already?

Yeah I managed to figure it out, thanks!@
