If your table rows are several KB in size, you may have a problem.
pg_column_size() measures the size in bytes.
In my experience the best measure is to create a table, fill it with some 10000
rows and divide the table size by the row count.
There is substantial overhead for each row, and there will be overhead and
fragmentation on the block level too.
