NAME

       pgcharts - PostgreSQL data loader

SYNOPSIS

       pgcharts [options] [command-file]...

DESCRIPTION

       pgcharts is The PostgreSQL Extension Installer server.

OPTIONS

       -h, --help
              Show command usage summary and exit.

       -V, --version
              Show pgcharts version string and exit.

       -c, --config
              Use the given configuration file (default to "~/.pgcharts.ini").

COMMANDS

       The pgcharts binary allows running and controling the pgcharts embedded web server.

   CONFIGURATION CONTROL
       While  it´s  possible to ship a configuration file or to prepare it by hand, the following
       commands allow to control the setup from the command line.

       •   config [ name ] [ value ]

           Without arguments, print the whole configuration file content. When given  a  variable
           name,  print  its  current  value.  When  given  both  a  name  and  a  value, set the
           configuration variable to the given value.

       •   config get <name>

           Print the current value of the configuration variable name.

       •   config set <name> <value>

           Set the variable name to the given value.

   SERVER CONTROL
       The PostgreSQL Extension Installer comes with a PostgreSQL plugin  that  downloads  static
       files:  that  part  doesn´t  need  any  server  at all. This server is meant to be used by
       maintainers of a set of extension archives, when they want to  ease  the  maintenance  and
       setup of the building.

       •   start

           Start  the  embedded  pgcharts  HTTP  server on the port it´s been setup to listen to,
           which defaults to 8042. The

       •   stop

           Stops the server.

       •   status

           Print the result of querying the HTTP  status  API  against  the  (hopefully)  running
           server.

       •   pid

           Print  the  registered  pid  of the server process. This information might be stale in
           case of unexpected termination of the server.

       •   setup <dburi>

           Connects to the PostgreSQL database specified with the dburi parameter and install the
           database model there.

   REGISTERING DATABASES
       Once  pgcharts  is properly setup (see the setup command above) then it´s necessary to add
       databases against which you want to run queries and draw charts.

       •   register <dburi>

           Register given dburi.

DATABASE URI

       The dburi connection string is expected to be given as a Connection URI as  documented  in
       the                     PostgreSQL                     documentation                    at
       http://www.postgresql.org/docs/9.3/static/libpq-connect.html#LIBPQ-CONNSTRING.

           postgresql://[user[:password]@][netloc][:port][/dbname][?sslmode=...]

       Where:

       •   user

           Can contain any character, including colon (:) which must then  be  doubled  (::)  and
           at-sign (@) which must then be doubled (@@).

           When  omitted, the user name defaults to the value of the PGUSER environment variable,
           and if it is unset, the value of the USER environment variable.

       •   password

           Can contain any character, including that at sign (@) which must then be doubled (@@).
           To leave the password empty, when the user name ends with at at sign, you then have to
           use the syntax user:@.

           When omitted, the password  defaults  to  the  value  of  the  PGPASSWORD  environment
           variable if it is set, otherwise the password is left unset.

       •   netloc

           Can  be  either  a  hostname  in dotted notation, or an ipv4, or an Unix domain socket
           path. Empty is the default network location, under  a  system  providing  unix  domain
           socket that method is preferred, otherwise the netloc default to localhost.

           It´s   possible   to   force   the  unix  domain  socket  path  by  using  the  syntax
           unix:/path/to/where/the/socket/file/is, so to force a non default socket  path  and  a
           non default port, you would have:

           postgresql://unix:/tmp:54321/dbname

       The  netloc  defaults to the value of the PGHOST environment variable, and if it is unset,
       to either the default unix socket path when  running  on  a  Unix  system,  and  localhost
       otherwise.

       •   dbname

           Should  be  a  proper  identifier (letter followed by a mix of letters, digits and the
           punctuation signs comma (,), dash (-) and underscore (_).

           When omitted, the dbname defaults to the value of the environment variable PGDATABASE,
           and if that is unset, to the user value as determined above.

       •   The  only  optional  parameter supported is sslmode and it accepts the values disable,
           allow, prefer and require.
