Ответ на need help separating a field  (Kevin Heflin <kheflin@shreve.net>)
Список pgsql-general
Well, I once split up a bunch of multiline addresses with lines like
this:

select "PerIndex",substr("addr",1,(strpos("addr",'\n')- 1)) as addr,
substr("addr",(str
pos("addr",'\n')+1)) as addr2 into tmp2_addr from tmp_addr;


so, try something like (untested):

select substr(username_password,1,(strpos(username_password,'/')-1)) as
username, substr(username_password,(strpos(username_password,'/')+1)) as
password into new_table from table;
