Functions with more than 32 parameters

Hi,

I am trying to keep database access encapsulated in functions from an insert
and update point of view so as all of the applications writing to the
database are using the same functions/statements.

My problem is I was creating functions to do inserts/updates and now I have
a table with more than 32 columns and the functions seem to only want to
have 32 parameters?

Is there any way around this?

I have used stored procedures in this way with Oracle/SQL server before.Or
is there another strategy I could use?

I am using Windows 2000 Postgres 8.0.1 if it makes a difference

Thanks in advance,
Oisin
