Functions have 32 args limt ???

Hi,

For my supprise I found that functions have 32 parameter limit.

Where to find more info about this limitation or similar limitations ?

I need at least 50, 100 would be ok.

varchar,varchar,varchar,varchar,varchar,varchar,varchar,varchar,varchar,varc
har,varchar,varchar,varchar,varchar,timestamp,timestamp,boolean,varchar,time
stamp,timestamp,boolean,varchar,varchar,timestamp,varchar,varchar,varchar,bo
olean)
