I have a table that has a column, properties, of type jsonb.


Based on documentation:


https://www.postgresql.org/docs/10/functions-json.html


To see all key / value pairs laid out as a table structure of columns, I can use function:


jsonb_each(jsonb) which returns:


"setof key text, value jsonb"


Also if I want to see just the keys, I can use function:


jsonb_object_keys(jsonb) which returns:


"Returns set of keys in the outermost JSON object."


, as per documentation.


So why does my output look like this:


SELECT jsonb_pretty(properties) as properties,jsonb_object_keys(properties) as keys,jsonb_each(properties) as json, properties::jsonb ? 'sendTo' as second FROM JMS_MESSAGE
FETCH FIRST 1 ROWS ONLY;
 properties | keys | json | second

(1 row)


The above jsonb_each and jsonb_object_keys both return only the first key. The boolean check if some key is in the jsonb column, (properties::jsonb ? 'sendTo'), returns true so I should see it in the returns for jsonb_each and json_object_keys.


Anyone know why I am not seeing all the keys in this row column?
