How is this better than "copy (...) to stdout"? E.g.:

$ copy (select * from pg_class limit 1) to stdout;
2619	pg_statistic	11	12016	0	10	2	2619	0	18	402	18	2840	t	f	p	r	31	0	f	f	f	f	f	t	n	f0	478	1	{postgres=arwdDxt/postgres}	\N	\N

You can still copy the necessary parts (using mouse selection) -
seems that it achieves the the same goal.

Best regards,
