Hello

now a most "hard" work is done and I would to enable access to new
error fields from plpgsql.

these new fields are column_name, constraint_name, datatype_name,
table_name and schema_name.

This proposal has impact on two plpgsql statements - RAISE and GET
STACKED DIAGNOSTICS.

I am sending initial implementation

Comments, notes?

Regards

Pavel
