* Maximum number of columns in an index and maximum number of arguments

* The minimum value is 9 (btree index creation has a 9-argument function).
*
* There is no maximum value, though if you want to pass more than 32
* arguments to a function, you will have to modify
* pgsql/src/backend/utils/fmgr/fmgr.c and add additional entries
* to the 'case' statement for the additional arguments.
