Problem parsing multidimensional json arrays about node-pg-types

[charmander]

Note that I haven't declared the column as a jsonb[][] because internally for postgres it should be treated the same.

Really…? I think you do need to declare it as a jsonb[][] if that’s what you want.

I think the documentation says otherwise. There are a lot of tools that actually depend on this behaviour as well such as PGAdmin. It won't even let you declare a column as jsonb[][] unless you over ride their gui and write a SQL query to declare the column type as such.

So is the current implementation the expected behaviour?
