Subject: [PATCH v1] Emit dummy statements for probes.d probes when disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.
