How to extract text from jsonb array in postgresql?

@brandy 

To extract text from a JSONB array in PostgreSQL, you can use the json_array_elements_text function. This function takes a JSONB array as input and returns each element of the array as text.

Here is an example:

1

SELECT json_array_elements_text('["apple", "banana", "orange"]'::jsonb);

This will return:

1
2
3
4
5

json_array_elements_text 
-------------------------
apple
banana
orange

You can also use the jsonb_array_elements_text function if you are working directly with a JSONB column in a table:

1

SELECT jsonb_array_elements_text(jsonb_column_name) FROM table_name;

This will return each element of the JSONB array stored in the jsonb_column_name column of the table_name table as text.
