Hello
 
I have a table created as the following
 
CREATE TABLE mod48_00_2007
(
  id text,
  n_gen serial NOT NULL,
  formstore text,
  te_cognome text,
  te_paternita text,
  te_nome text,
  te_sesso text,
  te_dtnasc text,
  te_attnasc text,
  te_luonasc text,
  te_provstato text,
  te_indi text,
  te_prov text,
  te_richiesta text,
  atto_forma text,
  rev_test text,
  atto_dt text,
  atto_num text,
  dt_olog text,
  cod_notaio text,
  pa_cognome text,
  pa_nome text,
  pa_qual text,
  pa_indirizzo text,
  pa_civ text,
  pa_cap text,
  pa_pro text,
  pa_sede text,
  pa_estero text,
  pa_data text,
  f_olo text,
  f_pub text,
  f_rev text,
  f_seg text,
  f_spe text,
  atto_riferimento text,
  ratto_dt text,
  ratto_num text,
  rdt_olog text,
  r_cognome text,
  r_nome text,
  r_qual text,
  r_sede text,
  r_estero text,
  dt_oggi text,
  n_pub_aut text,
  dt_tr_rgt text,
  sche_singola text,
  sche_multipla text,
  n_fog text,
  tot_n_fog text,
  reg_anno text,
  username text,
  date_inserted text,
  time_inserted text,
  deleted text,
  date_deleted text,
  time_deleted text,
  f_tes text,
  CONSTRAINT mod48_00_2007_pkey PRIMARY KEY (n_gen)
)
 
At a surtain point i need to replace a record with another
 
For example i have inserted 4 records. (1, 2 ,  3 , 4) I need to replace all the values from the record 4 to the record 2 but keeping the n_gen serial key. And then delete the record 4. So that the next record i insert will take the n_gen 4
 
How can i do this?
