[Postgres-xc-general] ERROR: Failed to get pooled connections

[Vladimir S. <vst...@gm...>]

I have fresh installed XC consisting of two data nodes with all defaults
settings. Nothing special was configured. I have created database and
one table with one only text field. Then I inserted text string and
tried SELECT. At this point all was OK. But after shutting down of one 
data node SELECT fails returning the message in subject. This is 
not what was I expected. DROP DATANODE doesn't help. If it is not a bug,
then I have questions:

1. What should failover and then recovery procedures be after one
data node fails?

2. Does this means, that XC is scalable in one only direction, that is
it can be expanded, but not shrunk? In other words, we cannot remove
data node.

3. Does this means, that without external infrastructure (like drbd +
corosync + pacemaker)  with default setup (CREATE TABLE ...
DISTRIBUTE BY REPLICATION) XC itself have no neither HA nor LB (at least
for writes) capabilities?

If all this true, it is not a cluster that I imagined after reading
XC description and what is expected from cluster at all.
