You are looking at why it is called, right? In gdb you can use the *up *command to look up the call stack to see what called something. That function, btw, will get called by anything that needs to deserialize agtype to agtype_value, even multiple times within a single agtype, due to nested structures. john On Mon, Jun 12, 2023 at 12:08 PM Panagiotis Foliadis <[email protected]> wrote: > Yes of course. > > When we run the basic select * from cypher > ('test', $$ create (u) return u) as (u agtype), fill_agtype_value() is > being called multiple times. > There are times when its called with the base_addr having the value > "idlabelproperties" and the offset > helps breaking down this string to fill correctly the json object that > will be return to the client.
