Function round(double precision, integer) does not exists trouble in 7.3.1, did work on 7.2.1

I am having trouble with a function round that used to work in 7.2.1

PostgreSQL was updated to 7.3.1 from 7.2.1, the data was re-loaded into
7.3.1 with no complaints from the DB engine but, at application run
time, we do get the error:

Function round(double precision, integer) does not exists

Code executed and that worked fine in 7.2.1 is:

selectclientes.id_cliente,clientes.codigo_cliente,clientes.total,clientes.deuda,clientes_pagos,total_pagos,
diferencia      from 
(
select clientes.id_cliente,clientes.codigo_cliente,clientes.total,clientes.deuda,(clientes.total-clientes.deuda) as
clientes_pagos,sum(sum)as total_pagos,       round((clientes.total-clientes.deuda)-sum(sum),4) as diferencia from    (
 select         codigo_cliente,         sum(total_pago)         from pagos        where estatus!='C'        group by
codigo_cliente 
    union    select         codigo_cliente,         sum(total_nota)        from notas_credito        where estatus!='C'
      group by codigo_cliente    )     as TT 
where codigo_cliente=clientes.codigo_clientegroup by
clientes.codigo_cliente,clientes.id_cliente,clientes.total,clientes.deuda,clientes_pagos
)
as TT1
where diferencia>0;


Question is, what changed in 7.3.1 in reference to the round function.

Tom Lane stated in a previous post (attached below) that "There isn't a
round(double, integer) function in 7.3 and there wasn't one in 7.2
either."    I am not so sure that is the case in our installation.

¿ How it can be explained then that it worked fine in a stock install
(rpm from RedHat Linux 7.3) of PostgreSQL 7.2.1 ?

Are we missing something here...?

Any comments or sugestions are welcome.
