Emit dummy statements for probes.d probes when disabled
When building without --enable-dtrace, emit dummy
do {} while (0)
statements for the stubbed-out TRACE_POSTGRESQL_foo() macros
instead of empty macros that totally elide the original probe
statement.
This fixes the
warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
introduced by b94409a02f
