Subject: [Tarantool-patches] [PATCH v4 07/16] sql: remove sql_vdbemem_finalize()
Date: Fri,  1 Oct 2021 15:48:43 +0300
Message-ID: <1642a14989ce8e691a0665a7baf43243cf93d009.1633092363.git.imeevma@gmail.com> (raw)
In-Reply-To: <cover.1633092363.git.imeevma@gmail.com>

We don't need this function, since it is easier to call finalizers
directly. This patch also allows us to make further simplifications.

Needed for #4145
