Graphql-engine: docs: guide on how to uninstall/purge hasura

[jflambert]

Dear Hasura people, we're using your amazing hasura.cli-migrations docker container but as part of a pipeline, I would need to completely kill any hasura objects in my database in order to rebuild them. Having some dependency issues at the moment (specifically INSTEAD OF triggers that seem to get created when granting some partial INSERT permissions)

Is it as simple as dropping the hdb_views and hdb_catalog schemas?

I would suggest adding this information to your also-amazing documentation.

Thanks!

@jflambert That is right. We should definitely add how to uninstall hasura in the docs.

The following should do the trick:

drop schema hdb_views cascade;
drop schema hdb_catalog cascade;
