commit cba9458319a2778a6472586fff67c7bd38f79181

Change current value of sequences to make it consistent with vanilla
In Postgres-XC (since the beginning of the project in 2009?), the current
value of sequences was taken directly from GTM. However, in vanilla postgres
this is maintained at session level, meaning that the current value of a
sequence inside a session is updated based on the cache maintained in it and
this cache is updated only each time nextval is called inside session.
This resulted in having currval being managed not at session level but at
a cluster level.
The "fix" here just consists in removing the GTM code for current value
management of sequences on GTM. By the way, it does not make sense to manage
that in a centralized way on GTM just knowing that currval is related to a
unique session between nodes.
This inconsistent behavior has been reported by Nikhil Sontakke.
I just cleaned up the code at the necessary places...

Get consistent sequence dump value with pg_dump
In Postgres-XC, the current value cached for a sequence may differ at node
level because of the shared-nothing nature of the cluster. Vanilla pg_dump
has been designed to take directly the current value of sequence from the
cache at node level, which is incorrect in XC and might lead to inconsistencies
if for example a dump is taken on a different node than where nextval has
been lastly called.
Report from Nikkhil Sontakke.
Nikhil proposed a fix which was not entirely consistent with Postgres
by using currval, so I created a solution with nextval to insure that
the correct and consistent cluster-wide value of sequence is taken for its
dump.
