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.
