Understand better what is supported with citus

[ammirator-administrator]

I did read the docs here https://hasura.io/docs/latest/databases/postgres/citus-hyperscale-postgres/hasura-citus-compatibility/#relationships

And my first question about citus relationships support is:

• Do we have to make ENUM tables also distributed? If these are used in a distributed table?
• what means (from local -> to reference)
• Computed fields are not supported at all? And why is that , is that somehow different than in postgres?
