[tarantool-patches] [PATCH 0/2] sql: add better coll. determination & position func.

[Ivan Koptelov]

There are two patches in this series. First one enhances
collation determination for function arguments (e.g. for cases,
when function arguments have different collations). Second one
renames instr() to position() and swaps arguments order. Also
after the second patch both arguments must have the same type,
which should be either TEXT or BLOB.
