Subject: [PATCH 15/18] dbtr: Move trigger feature support test into a function
Date: Fri, 13 Mar 2026 15:19:44 +1000	[thread overview]
Message-ID: <20260313051948.4017134-16-npiggin@gmail.com> (raw)
In-Reply-To: <20260313051948.4017134-1-npiggin@gmail.com>

With heterogeneous triggers this test becomes more complicated and is
neeed in more places, so move it into a function.
