If none of them is set, the default is to use more on most platforms, but less on Cygwin. If the form \dg+ is used, additional information is shown about each role; currently this adds the comment for each role. If access-method-pattern is specified, only operator families associated with access methods whose names match that pattern are listed. Otherwise, the new contents of the query buffer are re-parsed according to the normal rules of psql, treating the whole buffer as a single line.

Any additional arguments are type-name patterns, which are matched to the type names of the first, second, and so on arguments of the function. It is specified as a whitespace-separated list of values, e.g., '0.2 0.2 0.6'. If the expression yields true then processing continues normally; otherwise, lines are skipped until a matching \elif, \else, or \endif is reached.
