Surely tr will remove ALL the delimiters, so this is not helpful
unless these columns are the only ones in the table. You would
have to use awk or perl to process the exported file and delete
the correct delimiter.
For an SQL solution, how about:
SELECT col1, col2,..., areacode || phone as phone, colx, coly,...
INTO new_table
FROM table;
Then you can drop the old table and recreate it with the correct
columns and import the data into it from new_table. (You could
just rename new_table if it doesn't need to be created with
constraints.)
