How about (yet another) GUC, such as conform_pg_output ? If set to
true, commands will print only pg style information. But if set to
false, various commands may print a lot more XC-specific information.
The regression can be run with the GUC turned ON. I'm not sure what
should be the default. But it will make a lot of sense to keep it OFF
by default. This way, those who are coming from PG world don't need to
learn new commands.

Thanks,
Pavan
