Create a table with the same structure as your original table, just add a
sid int4 serial
column to it. (sid can be any column name you want it to be) The serial column
has to be at the end!
Then do a
INSERT INTO <new table> SELECT FROM <old table>
The serial column will automatically be set to 1,2,3,4,5 etc.
After that check if all the data made it to the new table and then you can
drop the old table and rename the new table to the name of the old table.
As usual I'd make a backup of the original table before doing all this.
