+#!/usr/bin/env bash
+#
+# Postgres-XC Configuration file for pgxc_ctl utility.
+#
+# Configuration file can be specified as -c option from pgxc_ctl command. Default is
+# $PGXC_CTL_HOME/pgxc_ctl.org.
+#
+# This is bash script so you can make any addition for your convenience to configure
+# your Postgres-XC cluster.
+#
+# Please understand that pgxc_ctl provides only a subset of configuration which pgxc_ctl
+# provide. Here's several several assumptions/restrictions pgxc_ctl depends on.
+#
+# 1) All the resources of pgxc nodes has to be owned by the same user. Same user means
+# user with the same user name. User ID may be different from server to server.
+# This must be specified as a variable $pgxcOwner.
+#
+# 2) All the servers must be reacheable via ssh without password. It is highly recommended
+# to setup key-based authentication among all the servers.
+#
+# 3) All the databases in coordinator/datanode has at least one same superuser. Pgxc_ctl
+# uses this user to connect to coordinators and datanodes. Again, no password should
+# be used to connect. You have many options to do this, pg_hba.conf, pg_ident.conf and
+# others. Pgxc_ctl provides a way to configure pg_hba.conf but not pg_ident.conf. This
+# will be implemented in the later releases.
+#
+# 4) Gtm master and slave can have different port to listen, while coordinator and datanode
+# slave should be assigned the same port number as master.
+#
+# 5) Port nuber of a coordinator slave must be the same as its master.
+#
+# 6) Master and slave are connected using synchronous replication. Asynchronous replication
+# have slight (almost none) chance to bring total cluster into inconsistent state.
+# This chance is very low and may be negligible. Support of asynchronous replication
+# may be supported in the later release.
+#
+# 7) Each coordinator and datanode can have only one slave each. Cascaded replication and
+# multiple slave are not supported in the current pgxc_ctl.
+#
+# 8) Killing nodes may end up with IPC resource leak, such as semafor and shared memory.
+# Only listening port (socket) will be cleaned with clean command.
+#
+# 9) Backup and restore are not supported in pgxc_ctl at present. This is a big task and
+# may need considerable resource.
+#
