Thanks a million for the explanation, Tom - that makes sense. I tried
what you suggested, with mixed results:
(i) Running the MERGE as a stand-alone query, with just RETURNING... ,
worked - I got a scalar and a row as expected.
(ii) Running it in a function (actually a DO block), with m_new
correctly declared as the table type, failed with the same error as before.
(iii) Running (ii) but with the order of the items in RETURNING reversed -
... returning t, merge_action() into m_new, m_action
- gave me a different error:
ERROR: record variable cannot be part of multiple-item INTO list
LINE 53: m, merge_action() into m_new, m_action
...which seems to answer my question definitively.
This:
... returning t, merge_action() into m_new, m_action
does not match this:
LINE 53: m, merge_action() into m_new, m_action
Is this a copy and paste error or two different invocations of the function?
Thanks once more,
Ray.
