This documentation is outright wrong.  The grain of truth behind the
statement is that the parser won't let you declare numeric(N) columns
with N > 1000.  But unconstrained numeric can be a lot larger.  The
hard limit of the format seems to be 10^128K.

I agree that a CHECK_FOR_INTERRUPTS in numeric_fac wouldn't be a bad
idea, and we can reject arguments that are clearly going to overflow.
