psql and INSERT/UPDATE/DELETE RETURNING

От

Currently, psql does not show the command completion tag if it gets a
PGRES_TUPLES_OK result.  This means you won't see the tag for a command
with RETURNING, eg

regression=# insert into int8_tbl values(1,2),(3,4);
INSERT 0 2
regression=# insert into int8_tbl values(1,2),(3,4) returning *;q1 | q2 
----+---- 1 |  2 3 |  4
(2 rows)

regression=# 

The tag is actually being sent by the backend, it's just not displayed.

Do we like this behavior?  The number-of-tuples part of the tag is
certainly redundant with the table display, but perhaps it's good to
have a reminder that the rows you are looking at were just INSERTed,
UPDATEd, or DELETEd.  I haven't checked the code but I imagine it'd
not be very difficult to change the behavior if we wish.

Comments?

Having both would be good :)
