.pgaw:Help.f.t insert end "  The " {} "Sequences" {bold} " tab is used to\
define new sequence number generators or to inspect them.

  Sequences are used sometimes for assigning default values to some unique\
fields in order to obtain a unique id. Sequences are returning an int4\
value. For example, a new sequence will be automatically defined if you\
are adding a 'serial' field type into a table.

  In order to define a new sequence you should supply at least the sequence\
name. The default increment is 1, the default start value and minvalue is 1.

  Inspecting a sequence will show you the last number generated.
