Array representation [pgAdmin4]

Hi Dave,

Regarding RM2641 how should we represent array data types; With curly braces (like pgAdminIII) or without curly braces (only comma separated)?

Currently in pgAdmin4 curly braces do not appear for text and int array data types however they do appear for real, bigint, float, etc array data types.

Also additional efforts will required If we plan to represent like pgAdminIII as we'll need to update/add slickgrid cell editors/formatter for array data types.
