Subject: [PATCH 3/5] index: optimize after all SQLite DB commits
Date: Tue, 12 Oct 2021 22:44:58 +0000	[thread overview]
Message-ID: <20211012224500.2882-4-e@80x24.org> (raw)
In-Reply-To: <20211012224500.2882-1-e@80x24.org>

This covers v1 inboxes, as well.  We also guard the execution
since "PRAGMA optimize" was only introduced in SQLite 3.18.0
