How to create a field with postgres schema definition

[Nik]

Turns out that dateTime defaults to timestamp without time zone while timestamp defaults to timestamp with time zone on postgres.

This definition is working now for me:

{
	field: 'time_of_call',
	type: 'dateTime',
	schema: {
		default_value: null,
		is_nullable: true
	},
	meta: {
		interface: 'datetime',
		display: 'datetime',
		display_options: {
			format: '24h',
		},
		note: 'Original datetime value from source',
	}
}

Doesn’t answer the initial question, tho, how to define a specific postgres field type.
