.SH "NAME"
\fBpgcharts\fR \- PostgreSQL data loader
.
.SH "SYNOPSIS"
\fBpgcharts\fR [\fIoptions\fR] [\fIcommand\-file\fR]\.\.\.
.
.SH "DESCRIPTION"
pgcharts is The PostgreSQL Extension Installer server\.
.
.SH "OPTIONS"
.
.TP
\fB\-h\fR, \fB\-\-help\fR
Show command usage summary and exit\.
.
.TP
\fB\-V\fR, \fB\-\-version\fR
Show pgcharts version string and exit\.
.
.TP
\fB\-c\fR, \fB\-\-config\fR
Use the given configuration file (default to "~/\.pgcharts\.ini")\.
.
.SH "COMMANDS"
The pgcharts binary allows running and controling the pgcharts embedded web server\.
.
.SS "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\.
.
.IP "\(bu" 4
\fBconfig [ name ] [ value ]\fR
.
.IP
Without arguments, print the whole configuration file content\. When given a variable \fIname\fR, print its current value\. When given both a \fIname\fR and a \fIvalue\fR, set the configuration variable to the given value\.
.
.IP "\(bu" 4
\fBconfig get <name>\fR
.
.IP
Print the current value of the configuration variable \fIname\fR\.
.
.IP "\(bu" 4
\fBconfig set <name> <value>\fR
.
.IP
Set the variable \fIname\fR to the given \fIvalue\fR\.
.
.IP "" 0
.
.SS "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\.
.
.IP "\(bu" 4
\fBstart\fR
.
.IP
Start the embedded pgcharts HTTP server on the port it\'s been setup to listen to, which defaults to 8042\. The
.
.IP "\(bu" 4
\fBstop\fR
.
.IP
Stops the server\.
.
.IP "\(bu" 4
\fBstatus\fR
.
.IP
Print the result of querying the HTTP status API against the (hopefully) running server\.
.
.IP "\(bu" 4
\fBpid\fR
.
.IP
Print the registered pid of the server process\. This information might be stale in case of unexpected termination of the server\.
.
.IP "\(bu" 4
\fBsetup <dburi>\fR
.
.IP
Connects to the PostgreSQL database specified with the \fIdburi\fR parameter and install the database model there\.
.
.IP "" 0
.
.SS "REGISTERING DATABASES"
Once pgcharts is properly setup (see the \fBsetup\fR command above) then it\'s necessary to add databases against which you want to run queries and draw charts\.
.
.IP "\(bu" 4
\fBregister <dburi>\fR
.
.IP
Register given \fIdburi\fR\.
.
.IP "" 0
.
.SH "DATABASE URI"
The \fIdburi\fR connection string is expected to be given as a \fIConnection URI\fR as documented in the PostgreSQL documentation at http://www\.postgresql\.org/docs/9\.3/static/libpq\-connect\.html#LIBPQ\-CONNSTRING\.
.
.IP "" 4
.
.nf

postgresql://[user[:password]@][netloc][:port][/dbname][?sslmode=\.\.\.]
.
.fi
.
.IP "" 0
.
.P
Where:
.
.IP "\(bu" 4
\fIuser\fR
.
.IP
Can contain any character, including colon (\fB:\fR) which must then be doubled (\fB::\fR) and at\-sign (\fB@\fR) which must then be doubled (\fB@@\fR)\.
.
.IP
When omitted, the \fIuser\fR name defaults to the value of the \fBPGUSER\fR environment variable, and if it is unset, the value of the \fBUSER\fR environment variable\.
.
.IP "\(bu" 4
\fIpassword\fR
.
.IP
Can contain any character, including that at sign (\fB@\fR) which must then be doubled (\fB@@\fR)\. To leave the password empty, when the \fIuser\fR name ends with at at sign, you then have to use the syntax user:@\.
.
.IP
When omitted, the \fIpassword\fR defaults to the value of the \fBPGPASSWORD\fR environment variable if it is set, otherwise the password is left unset\.
.
.IP "\(bu" 4
\fInetloc\fR
.
.IP
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 \fIunix domain socket\fR that method is preferred, otherwise the \fInetloc\fR default to \fBlocalhost\fR\.
.
.IP
It\'s possible to force the \fIunix domain socket\fR path by using the syntax \fBunix:/path/to/where/the/socket/file/is\fR, so to force a non default socket path and a non default port, you would have:
.
.IP "" 4
.
.nf

postgresql://unix:/tmp:54321/dbname
.
.fi
.
.IP "" 0
.
.IP
The \fInetloc\fR defaults to the value of the \fBPGHOST\fR environment variable, and if it is unset, to either the default \fBunix\fR socket path when running on a Unix system, and \fBlocalhost\fR otherwise\.
.
.IP "\(bu" 4
\fIdbname\fR
.
.IP
Should be a proper identifier (letter followed by a mix of letters, digits and the punctuation signs comma (\fB,\fR), dash (\fB\-\fR) and underscore (\fB_\fR)\.
.
.IP
When omitted, the \fIdbname\fR defaults to the value of the environment variable \fBPGDATABASE\fR, and if that is unset, to the \fIuser\fR value as determined above\.
.
.IP "\(bu" 4
The only optional parameter supported is \fBsslmode\fR and it accepts the values \fBdisable\fR, \fBallow\fR, \fBprefer\fR and \fBrequire\fR\.
