Обсуждение: pgsql: Fix pg_get_functiondef() to print a function's LEAKPROOF propert

Fix pg_get_functiondef() to print a function's LEAKPROOF property.

Seems to have been an oversight in the original leakproofness patch.
Per report and patch from Jeevan Chalke.

In passing, prettify some awkward leakproof-related code in AlterFunction.
