PG_VIRTUALENV(1)       Debian PostgreSQL infrastructure	      PG_VIRTUALENV(1)

NAME
       pg_virtualenv - Create a throw-away PostgreSQL environment for running
       regression tests

SYNOPSIS
       pg_virtualenv [OPTIONS] [-v 'version ...'] [command]

DESCRIPTION
       pg_virtualenv creates a virtual PostgreSQL server environment, and sets
       environment variables such that command can access the PostgreSQL
       database server(s). The servers are destroyed when command exits.

       The environment variables PGHOST, PGDATABASE, PGUSER, and PGPASSWORD
       will be set. Per default, a single new cluster is created, using the
       newest PostgreSQL server version installed. The cluster will use the
       first available port number starting from 5432, and PGPORT will be set.

       When clusters for more than one versions are created, they will differ
       in the port number used, and PGPORT is not set. The clusters are named
       version/regress. To access a cluster, set PGCLUSTER=version/regress.
       For ease of access, the clusters are also registered in
       /etc/postgresql-common/pg_service.conf, with the version number as
       cluster name. Clusters can be accessed by passing the connection string
       "service=version", e.g. psql service=9.2.

       When invoked as root, the clusters are created in /etc/postgresql/ as
       usual; for other users, PG_CLUSTER_CONF_ROOT and PGSYSCONFDIR are set
       to a temporary directory where all files belonging to the clusters are
       created.

OPTIONS
       -a  Use all PostgreSQL server versions installed.

       -v version ...
	   Use these versions (space-separated list).

       -c pg_createcluster options
	   Extra options to pass to pg_createcluster.

       -i initdb options
	   Extra initdb options to pass to pg_createcluster.

       -o guc=value
	   Configuration option to set in the postgresql.conf file, passed to
	   pg_createcluster.

       -s  Launch a shell inside the virtual environment when command fails.

       -t  Install clusters in a temporary directory, even when running as
	   root.

       -h  Show program help.

EXAMPLE
	 # pg_virtualenv make check

NOTES
       When run with fakeroot(1), pg_virtualenv will fall back to the non-root
       mode of operation. Running "fakeroot pg_virtualenv" as root will fail,
       though.

ENVIRONMENT
       PG_VIRTUALENV_NEWPID=yes
	   When non-empty, pg_virtualenv will re-exec itself using newpid(1).

       PG_VIRTUALENV_UNSHARE=flags
	   When non-empty, pg_virtualenv will re-exec itself using unshare(1)
	   using these flags.

       PGPORT=n
	   When set, the value is used for the (single) cluster created.

SEE ALSO
       initdb(1), pg_createcluster(1).
