ProcedureCreate neglected to record dependencies on default expressions.

tglsfdc · tglsfdc · commit 50af47f12bb8 · 2011-10-03T12:13:53.000-04:00
Thus, an object referenced in a default expression could be dropped while
the function remained present.  This was unaccountably missed in the
original patch to add default parameters for functions.  Reported by
Pavel Stehule.
