Show gdb PrettyPrinters output in tree like structure

[ivan-v-kush]

Is it possible to see gdb PrettyPrinters output in tree like structure in Variables view?

I have a C-code with C-like inheritance. RestrictInfo is derived struct from Node. In variables window I'd like that node will show RestrictInfo data.

I've tried several formats, but nothing has worked. Node is seen as a string, not tree-like structure. RetrictInfo is seen like a tree.

1. Like in gdb output for structs:

 {type = T_RestrictInfo, clause = 0x5a3d244552f0, is_pushed_down = true}

Node node named clause on the screenshot. rinfo is RestrictInfo

2. json-output

{type: "T_RestrictInfo", clause: "0x5a3d244552f0", is_pushed_down: true}

C-code

typedef struct Node
{
	NodeTag		type;
} Node;


typedef struct RestrictInfo
{
	NodeTag		type;

	Expr	   *clause;			/* the represented clause of WHERE or JOIN */

	bool		is_pushed_down; /* true if clause was pushed down in level */

	bool		outerjoin_delayed;	/* true if delayed by lower outer join */
} RestrictInfo;


RestrictInfo *rinfo = ..... //make and fill RestrictInfo

Node *node = rinfo
