OK. MHO is that __attribute__((unused)) is probably less annoying than
#ifdef overall. Also, it occurs to me that an intermediate macro
"PG_USED_FOR_ASSERTS_ONLY" would be a good idea, first because it
documents *why* you want to mark the variable as possibly unused,
and second because changing the macro definition would provide an easy way
to check for totally-unused variables, in case we wanted to periodically
make such checks.
This is all modulo the question of what pgindent will do with it,
which I would still like to see tested before we commit to a method.
