Max input parameter for a function

Dear friends,

While trying to allocate about 36 input parameters, I got an error saying that the max input parameter for a function is only 32.

Is it right? How to overcome this? Because I wanna insert records into a table of 55 columns with a lot of NULL able columns.

I am using Postgres 7.3.4 on RH Linux 7.2.

Note: I can't use 2 functions , one to insert 32 rows into the table first and the update the remaining columns with other function. Because there are only 27 columns that are not null.

Please shed some light.

Regards
Kumar
