Re: boolean to int

Hello, you can use own cast.

create or replace function int2bool (integer) returns boolean as '
  select case when $1=1 then ''t''::boolean else ''f''::boolean end;
' language sql;

create or replace function bool2int (boolean) returns integer as '
  select case when $1 then 0 else 1 end; ' language sql;

create cast (integer as boolean) with function int2bool(integer)
  as implicit;

create cast (boolean as integer) with function bool2int(boolean)
  as implicit;
