Suppress uninitialized-variable warning.
In the wake of commit 80aa9848b, a few compilers think that
postgresAcquireSampleRowsFunc's "reltuples" might be used
uninitialized. The logic is visibly correct, both before
and after that change; presumably what happened here is that
the previous presence of a setjmp() in the function stopped
them from attempting any flow analysis at all. Add a dummy
initialization to silence the warning.
