Primary Key in column definition of entity

[ronic09]

Hello! I am using cottontail for my master thesis. Thank you for your work! It seems to me that the primary flag in the column definition of an entity has no effect. It is possible to insert multiple entries with the same string ID into an entity with primary key set for the column. Furthermore, the CLI command "entity about schema entity" does not list primary information for the columns.

Best, Simon
