-.SH DESCRIPTION
-The interactive terminal monitor is a simple frontend to Postgres retained
-for backwards compatiblity. Users are encouraged to the use the
-.IR "psql"
-interface instead.
-.PP
-.IR "monitor"
-enables you to formulate, edit and review queries before issuing them
-to Postgres. If changes must be made, a Unix editor may be called
-to edit the
-.BR "query buffer"
-managed by the terminal monitor. The editor used is determined by the
-value of the
-.SM EDITOR
-environment variable. If
-.SM EDITOR
-is not set, then
-.BR "vi"
-is used by default.
-.PP
-.IR "Monitor"
-is a frontend application, like any other. Hence, a
-.IR "postmaster"
-process must be running on the database server host before
-.IR "monitor"
-is executed. In addition, the correct
-.IR "postmaster"
-port number must be specified
-as described below.
-.PP
-The optional argument
-.IR dbname
-specifies the name of the database to be accessed. This database must
-already have been created using
-.IR createdb .
-.IR Dbname
-defaults to the value of the
-.SM USER
-environment variable.
-.PP
-.IR "Monitor"
-understands the following command-line options:
-.TP 5n
-.BR "-N"
-Specifies that query results will be dumped to the screen without any
-attempt at formatting. This is useful in with the
-.BR -c
-option in shell scripts.
-.TP
-.BR "-Q"
-Produces extremely unverbose output.
-This is useful
-with the
-.BR -c
-option in shell scripts.
-.TP
-.BR "-T"
-Specifies that attribute names will not be printed.
-This is useful
-with the
-.BR -c
-option in shell scripts.
-.TP
-.BR "-a" " system"
-Specifies an authentication system
-.IR "system"
-(see
-.IR pgintro (1))
-to use in connecting to the
-.IR postmaster
-process. The default is site-specific.
-.TP
-.BR "-c" " query"
-Specifies that
-.IR "monitor"
-is to execute one query string,
-.IR "query" ,
-and then exit. This is useful for shell scripts, typically in
-conjunction with the
-.BR -N
-and
-.BR -T
-options. Examples of shell scripts in the Postgres distribution using
-.IB "monitor" " -c"
-include
-.IR createdb ,
-.IR destroydb ,
-.IR createuser ,
-and
-.IR destroyuser ,
-.TP
-.BR "-d" " path"
-.IR path
-specifies the path name of the file or tty to which frontend (i.e.,
-.IR monitor )
-debugging messages are to be written; the default is not to generate
-any debugging messages.
-.TP
-.BR "-h" " hostname"
-Specifies the hostname of the machine on which the
-.IR postmaster
-is running. Defaults to the name of the local host, or the value of
-the
-.SM PGHOST
-environment variable (if set).
-.TP
-.BR "-p" " port"
-Specifies the Internet TCP port on which the
-.IR postmaster
-is listening for connections. Defaults to 5432, or the value of the
-.SM PGPORT
-environment variable (if set).
-.TP
-.BR "-q"
-Specifies that the monitor should do its work quietly. By default, it
-prints welcome and exit messages and the queries it sends to the
-backend. If this option is used, none of this happens.
-.TP
-.BR "-t" " tty_device"
-.IR "tty_device"
-specifies the path name to the file or tty
-to which backend (i.e.,
-.IR postgres )
-debugging messages are to be written; the default is
-.IR "/dev/null" .
-.TP
-.BR "-s"
-parses after each query (enables "single step" mode).
-.TP
-.BR "-S"
-Turns off sending query when ";" is encountered.
-.PP
-You may set environment variables to avoid typing some of the above
-options. See the
-.SM "ENVIRONMENT VARIABLES"
-section below.
-.SH "MESSAGES AND PROMPTS"
-The terminal monitor gives a variety of messages to keep the user
-informed of the status of the monitor and the query buffer.
-.PP
-The terminal monitor displays two kinds of messages:
-.IP go
-The query buffer is empty and the terminal monitor is ready for input.
-Anything typed will be added to the buffer.
-.IP *
-This prompt is typed at the beginning of each line when the terminal
-monitor is waiting for input.
-.SH "TERMINAL MONITOR COMMANDS"
-.IP \ee
-Enter the editor to edit the query buffer.
-.IP \eg
-Submit query buffer to Postgres for execution.
-.IP \eh
-Get on-line help.
-.IP "\ei \fIfilename\fR"
-Include the file
-.IR filename
-into the query buffer.
-.IP \ep
-Print the current contents of the query buffer.
-.IP \eq
-Exit from the terminal monitor.
-.IP \er
-Reset (clear) the query buffer.
-.IP \es
-Escape to a Unix subshell. To return to the terminal monitor, type
-\*(lqexit\*(rq at the shell prompt.
-.IP \et
-Print the current time.
-.IP "\ew \fIfilename\fR"
-Store (write) the query buffer to an external file
-.IR filename .
-.IP \e\e
-Produce a single backslash at the current location in query buffer.
-.IP \e;
-Produce a single semi-colon at the current location in query buffer.
-.SH "ENVIRONMENT VARIABLES"
-You may set any of the following environment variables to avoid
-specifying command-line options:
-.nf
-hostname: PGHOST
-port: PGPORT
-tty: PGTTY
-options: PGOPTION
-realm: PGREALM
-.fi
-.PP
-If
-.SM PGOPTION
-is specified, then the options it contains are parsed
-.BR before
-any command-line options.
-.PP
-.SM PGREALM
-only applies if
-.IR Kerberos
-authentication is in use. If this environment variable is set, Postgres
-will attempt authentication with servers for this realm and use
-separate ticket files to avoid conflicts with local ticket files. See
-.IR pgintro (1)
-for additional information on
-.IR Kerberos .
-.PP
-See
-.IR pgintro (libpq)
-for additional details.
-.SH "RETURN VALUE"
-When executed with the
-.BR "-c"
-option,
-.IR monitor
-returns 0 to the shell on successful query completion, 1 otherwise.
-.SH "SEE ALSO"
-libpq(3),
-createdb(1),
-createuser(1),
-postgres(1),
-postmaster(1).
-.SH BUGS
-Does not poll for asynchronous notification events generated by
-.IR listen (l)
-and
-.IR notify (l).

-Escapes (backslash characters) cannot be commented out.
