Hello.
I have a variable with a field name and want to extract this field
value from NEW record:
DECLARE
field VARCHAR = 'some_field';
BEGIN
...
value := NEW.{field}; -- ???
END;
Is it possible in pl/pgsql?
I have found one speed-inefficient solution: convert NEW to string and
then - use EXECURE with customly-build query to extract a value from
that constant string. But it is too slow. Is there better solution?
