Here is a new psql \? output format that I would like to add for 7.4.
It follows Harald Armin's suggested reformatting, which you can see
below.

Should I also reorder the psql manual page to match?  I find the
grouping much easier to review.

General
 \c[onnect] [DBNAME|- [USER]]
                connect to new database (currently "test")

 \! [COMMAND]   execute command in shell or start interactive shell
 \encoding [ENCODING]  show or set client encoding
 \set [NAME [VALUE]]  set internal variable, or list all if no parameters
 \unset NAME    unset (delete) internal variable
 \timing        toggle timing of commands (currently off)

Query Buffer
 \g [FILE]      send query buffer to server (and results to file or |pipe)
 \r             reset (clear) the query buffer
 \e [FILE]      edit the query buffer (or file) with external editor
 \i FILE        execute commands from file
 \p             show the contents of the query buffer
 \w [FILE]      write query buffer to file
 \o FILE        send all query results to file or |pipe
 \s [FILE]      display history or save it to file

Informational
 \d [NAME]      describe table, index, sequence, or view
 \d{t|i|s|v|S} [PATTERN] (add "+" for more detail)

 \da [PATTERN]  list aggregate functions
 \dd [PATTERN]  show comment for object
 \dD [PATTERN]  list domains
 \df [PATTERN]  list functions (add "+" for more detail)
 \do [NAME]     list operators
 \dl            list large objects, same as \lo_list
 \dp [PATTERN]  list table access privileges
 \dT [PATTERN]  list data types (add "+" for more detail)
 \du [PATTERN]  list users
 \l             list all databases (add "+" for more detail)
 \z [PATTERN]   list table access privileges (same as \dp)

Large Object, Copy
 \lo_export
 \lo_import
 \lo_list
 \lo_unlink     large object operations
 \copy ...      perform SQL COPY with data stream to the client host

 \a             toggle between unaligned and aligned output mode
 \f [STRING]    show or set field separator for unaligned query output
 \t             show only rows (currently off)
 \echo [STRING] write string to standard output
 \qecho [STRING]  write string to query output stream (see \o)

HTML Output
 \H             toggle HTML output mode (currently off)
 \C [STRING]    set table title, or unset if none
 \T [STRING]    set HTML <table> tag attributes, or unset if none
 \pset NAME [VALUE]  set table output option
                (NAME := {format|border|expanded|fieldsep|null|recordsep|
                tuples_only|title|tableattr|pager})
