The Postgres jsonb_to_record() function takes a top-level JSONB object, converts it into a table record/row, and returns it.

PL/pgSQL supports block structure. The block has two sections; a declaration and a body. Sub-block structure is also supported by PL/pgSQL.

The JSONB object is provided to the jsonb_object_keys() function as an argument and it returns a column containing all the keys present in that particular JSONB object.

The jsonb_insert() function inserts a new JSONB value into an already existing JSONB object at a specific location. It takes in 3 parameters essentially and 1 parameter optionally.

The jsonb_pretty() function returns the beautified version of the provided JSONB value. This function applies proper formatting to the given value.

The json_populate_record() function in Postgres converts the JSON object into a data row. It populates the table record from the JSON object.

The json_populate_recordset() function converts the JSON array into a set of data rows. The JSON array can contain multiple JSON objects, which can be converted into arrays by using it.
