[Tarantool-patches] [PATCH v3 0/3] sql: fix order of inserted rows

[imeevma@tarantool.org]

This patch-set fixes order of inserted rows in case ephemeral
space is used during INSERT into space with sequence. The order
now is the same in which these values were inserted originally.
Wrong order could lead to an error in case NULL was inserted into
field with sequence.
