[Tarantool-patches] [PATCH 0/3] sql: modify explicit conversion tables

[Timur Safin]

Recent RFC "Consistent Lua/SQL types" (#6009) defined ideal explicit
and implicit conversion tables we would like to have for all current 
and future Taranool SQL types. 

This patchset modifies explict conversion tables, and implicit 
conversion table to come soon. The ideal picture would be as below:

              | 0 | 1 | 2 | 4 | 5 | 6 | 7 | 3 | 9 |10 |11 |12 | 8 |
              +---+---+---+---+---+---+---+---+---+---+---+---+---+
 0.       any |   |   |   |   |   |   |   |   |   |   |   |   |   |
 1.  unsigned |   | Y | Y | Y | Y |   |   | Y |   |   |   |   | Y |
 2.    string |   | S | Y | S | S | S | Y | S |   |   |   |   | Y |
 4.    double |   | S | Y | Y | S |   |   | Y |   |   |   |   | Y |
 5.   integer |   | S | Y | Y | Y |   |   | Y |   |   |   |   | Y |
 6.   boolean |   |   | Y |   |   | Y |   |   |   |   |   |   | Y |
 7. varbinary |   |   | Y |   |   |   | Y |   |   |   |   |   | Y |
 3.    number |   | S | Y | Y | S |   |   | Y |   |   |   |   | Y |
 9.   decimal |   |   |   |   |   |   |   |   |   |   |   |   |   |
10.      uuid |   |   |   |   |   |   |   |   |   |   |   |   |   |
11.     array |   |   |   |   |   |   |   |   |   |   |   |   |   |
12.       map |   |   |   |   |   |   |   |   |   |   |   |   |   |
 8.    scalar |   | S | Y | S | S | S | S | S |   |   |   |   | Y |
              +---+---+---+---+---+---+---+---+---+---+---+---+---+

Please pay attention that we omit DECIMAL, UUID, SCALAR and MAP rows
and columns, as they not yet fully supported by Tarantool SQL. Once 
their support will be landed we will modify conversion table and 
tests (which we also introducing with current patchset).
