Personally, as a heavy user of PL/pgSQL procedures, I'm not sure youneed to increase the *default* number of
parameters. Postgres justneeds to implement a parameter number change as part of a documentedcommand-line compile-time
option,i.e. "--with-parameters=32". Currently, increasing the number of parameters requires altering theC config files
beforecompilation, a rather user-hostile process.  
 

I've raised this point 3 or 4 times on this list now, and have not seena respons from you or Thomas on this suggestion.
 If I had theskills, I'd do it myself and upload the changes, but C is not mystrong suit.
 

Also, what is the practical maximum number of parameters?
