Hi, I have a question about transactions, i readed that postgres-xc doesn't support savepoints. What happens if transaction fails ? My application use postgreSQL and implement savepoint dao class with create savepoint in database. I want to migrate from postgreSQL to postgres-xc and i don't know what to do in this situation. Regards |

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. --- Koichi Suzuki On 2013/07/21, at 22:46, Michael Paquier <mic...@gm...> wrote: > > > > On Sun, Jul 21, 2013 at 10:10 PM, Tomasz Straszewski <str...@gm...> wrote: > W dniu 2013-07-21 00:01, Michael Paquier pisze: >> >> >> >> On Sun, Jul 21, 2013 at 12:24 AM, Tomasz Straszewski <str...@gm...> wrote: >> Hi, >> >> I have a question about transactions, i readed that postgres-xc doesn't >> support savepoints.

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...
