Hello all,

I use postgresql 9.5 and I am looking for way to have a column which is an array of a foreign key. If what I read is correct it is currently not possible... Have you any idea how to implement this feature in a safe way (foreign key constraints) ?

I don't have another idea to have a enum array....

Thank you

Thomas
