Most SQLA engines are unbounded for the
TEXTtype however for MySQL it's restricted to ~ 64 kB which can cause overflow for thedashboards.position_jsoncolumn for the V2 layout.This PR ensures that for MySQL engines the
TEXTcolumn is changed fromTEXT(~ 64 kB) toMEDIUMTEXT(~ 16 MB). All other engines remained unchanged.to: @graceguo-supercat @michellethomas @mistercrunch @williaster
