How to convert GeoJSON geodata to PostGIS?

Question

PostgreSQL

Can you tell me how to convert GeoJSON coordinates to PostGIS coordinates suitable for a Geometry column?
I have a table with imported from xm; file with data and coordinates in it in GeoJSON.
I read, read - I roughly understand that you need to use
UPDATE
SELECT
ST_GeomFromGeoJSON
ST_SetSRID - 4326
I can get data with such a request

SELECT ST_SetSRID(ST_GeomFromGeoJSON('{"type":"Polygon","coordinates":[]}'),4326);

It seems like this is what I need, but I don’t understand how to change it in the entire table.
Who is not difficult - tell me how to convert geodata.
Geo_coordinates column
Thank you))
And is it possible to change the type of the column in geometry after the conversion, or do I need to create a new table and copy the data?
Thanks
