NAME

       pg_wrapper - wrapper for PostgreSQL client commands

SYNOPSIS

       client-program [--cluster version/cluster] [...]

       (client-program: psql, createdb, dropuser, and all other client programs installed in /usr/lib/postgresql/version/bin).

DESCRIPTION

       This program is run only as a link to names which correspond to PostgreSQL programs in /usr/lib/postgresql/version/bin. It determines the
       configured cluster and database for the user and calls the appropriate version of the desired program to connect to that cluster and
       database, supplying any specified options to that command.

       The target cluster is selected by the following means, in descending order of precedence:

       1.  explicit specification with the --host option

       2.  explicit specification with the --cluster option

       3.  if the PGHOST environment variable is set, no further cluster selection is performed. The default PostgreSQL version and port number
	   (from the command line, the environment variable PGPORT, or default 5432) will be used.

       4.  explicit specification with the PGCLUSTER environment variable

       5.  matching entry in ~/.postgresqlrc (see postgresqlrc(5)), if that file exists

       6.  matching entry in /etc/postgresql-common/user_clusters (see user_clusters(5)), if that file exists

       7.  If only one local cluster exists, that one will be selected.

       8.  If several local clusters exist, the one listening on the default port 5432 will be selected.

       If none of these rules match, pg_wrapper aborts with an error.

OPTIONS

       --cluster version/cluster
	   cluster is either the name of a local cluster, or takes the form host:port for a remote cluster. If port is left empty (i. e. you just
	   specify host:), it defaults to 5432.

ENVIRONMENT

       PGCLUSTER
	   If $PGCLUSTER is set, its value (of the form version/cluster) specifies the desired cluster, similar to the --cluster option. However,
	   if --cluster is specified, it overrides the value of $PGCLUSTER.

       PG_CLUSTER_CONF_ROOT
	   This specifies an alternative base directory for cluster configurations. This is usually /etc/postgresql/, but for testing/development
	   purposes you can change this to point to e. g. your home directory, so that you can use the postgresql-common tools without root
	   privileges.

FILES

       /etc/postgresql-common/user_clusters
	   stores the default cluster and database for users and groups as set by the administrators.

       $HOME/.postgresqlrc
	   stores defaults set by the user himself.

       user_clusters(5), postgresqlrc(5)

NAME

       cmruncl - run a high availability cluster

SYNOPSIS

       cmruncl [-f] [-v] [-n node_name...]  [-t | -w none]

DESCRIPTION

       cmruncl causes all nodes in a configured cluster or all nodes specified to start their cluster daemons and form a new cluster.

       To  start  a  cluster,  a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the cluster configuration
       file. See access policy in cmquerycl(1m).

       This command should only be run when the cluster is not active on any of the configured nodes.  This command verifies the network  configu-
       ration  before  causing	the nodes to start their cluster daemons.  If a cluster is already running on a subset of the nodes, the cmrunnode
       command should be used to start the remaining nodes and force them to join the existing cluster.

       If node_name is not specified, the cluster daemons will be started on all the nodes in the cluster.  All  nodes	in  the  cluster  must	be
       available for the cluster to start unless a subset of nodes is specified.

   Options
       cmruncl supports the following options:

	      -f	Force cluster startup without warning message and continuation prompt that are printed with the -n option.

	      -v	Verbose output will be displayed.

	      -t	Test  only.  Provide  an assessment of the package placement without affecting the current state of the nodes or packages.
			The -w option is not required with the -t option as -t does not validate network connectivity, but assumes  that  all  the
			nodes can meet any external dependencies such as EMS resources, package subnets, and storage.

	      -n  node_name...
			Start the cluster daemon on the specified subset of node(s).

	      -w none	By default network probing is performed to check that the network connectivity is the same as when the cluster was config-
			ured. Any anomalies are reported before the cluster daemons are started. The -w none option  disables  this  probing.  The
			option should only be used if this network configuration is known to be correct from a recent check.

       RETURN VALUE
	      cmruncl returns the following value:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       Run the cluster daemon:

	      cmruncl

       Run the cluster daemons on node1 and node2:

	      cmruncl -n node1 -n node2
