Обсуждение: JSON_TABLE output collations

The present implementation of JSON_TABLE sets the collation of the 
output columns to the default collation if the specified data type is 
collatable.  Why don't we use the collation of the type directly?  This 
would make domains with attached collations work correctly.

See attached patch for how to change this.  I hacked up a regression 
test case to demonstrate this.
