postgres-xc-general Mailing List for Postgres-XC

Hi,
Thanks for replies ;-),

So are chances to add this feature into the project?
Now i must use Pgpool-II to creating load balancing fuctionality ( in 
master-salve configuration :/), configuration master-master in this case 
will be much better...

Regards,

Attempt to create savepoint will return "Not Supported" error, so the
transaction aborts at the point where you create the savepoint.

Priority depends upon how it is demanded.  Yes, so far, the priority is not high.  On the other hand, I expect the development effort is not too much.
