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_pretty() function returns the beautified version of the provided JSONB value. This function applies proper formatting to the given value.
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 to_ascii() function in PostgreSQL converts the provided string from any valid encoding to the ASCII encoding.
The trim_scale() function takes in a value of a numeric data type and returns the number after trimming zeros from the decimal part of the given numeric value.
In PostgreSQL, the jsonb_build_array() function takes the list of heterogeneous parameters and builds the JSONB array from them.
While writing the PostgreSQL queries, we sometimes need to use the string as identifiers. For this purpose, the string needs to be converted into the quantified identifier or properly quoted in the double quotation mark. In PostgreSQL, the quote_ident() function performs this task. The quote_ident() function gets a string as an argument and returns the same string properly double-quoted that can be used as a qualified identifier.

The min_scale() function in Postgres returns the minimum precision or minimum number of decimal places that are necessary to accurately/completely express the number.
parse_ident() function splits the qualified identifier/argument into an array. It gets two parameters; the 1st is the argument that is to be split, and the 2nd is the strict mode
The json_each() function converts the top-level JSON object into the expanded key-value pairs. It accepts a JSON object as an input and converts and returns the expanded key-value pairs.
