The configure script seems to prefer this version of Python over any others,
so you may experience linker problems as described in:
http://osdir.com/ml/pgsql-general/2009-09/msg00160.html
To fix this issue, you may need to either delete the version of Python
shown above, or move it out of the way before brewing PostgreSQL.
Note that a framework Python in /Library/Frameworks/Python.framework is
the "MacPython" version, and not the system-provided version which is in:
/System/Library/Frameworks/Python.framework

To get started with Postgres-XC, read the documents at
http://sourceforge.net/projects/postgres-xc/files/Publication/
http://postgres-xc.sourceforge.net/docs/1_0/tutorial-start.html
For a first cluster, you may start with a single GTM (Global Transaction Manager),
a pair of Data Nodes and a single Coordinator, all on the same machine:
initgtm -Z gtm -D #{var}/postgres-xc/gtm
initdb -D #{var}/postgres-xc/datanode1 --nodename datanode1
initdb -D #{var}/postgres-xc/datanode2 --nodename datanode2
initdb -D #{var}/postgres-xc/coord --nodename coord
Then edit:
#{var}/postgres-xc/datanode1/postgresql.conf
#{var}/postgres-xc/datanode2/postgresql.conf
and change the port to 15432 and 15433, respectively.
Then, launch the nodes and connect to the coordinator:
gtm -D #{var}/postgres-xc/gtm -l #{var}/postgres-xc/gtm/server.log &
postgres -i -X -D #{var}/postgres-xc/datanode1 -r #{var}/postgres-xc/datanode1/server.log &
postgres -i -X -D #{var}/postgres-xc/datanode2 -r #{var}/postgres-xc/datanode2/server.log &
postgres -i -C -D #{var}/postgres-xc/coord -r #{var}/postgres-xc/coord/server.log &
psql postgres
create node datanode1 with (type='datanode', port=15432);
create node datanode2 with (type='datanode', port=15433);
select * from pgxc_node;
select pgxc_pool_reload();
To shutdown everything, kill the processes in reverse order:
kill -SIGTERM `head -1 #{var}/postgres-xc/coord/postmaster.pid`
kill -SIGTERM `head -1 #{var}/postgres-xc/datanode1/postmaster.pid`
kill -SIGTERM `head -1 #{var}/postgres-xc/datanode2/postmaster.pid`
kill -SIGTERM `head -1 #{var}/postgres-xc/gtm/gtm.pid`
If you get the following error:
FATAL: could not create shared memory segment: Cannot allocate memory
then you need to tweak your system's shared memory parameters:
