       _g_._c_o_l_u_m_n_._p_g  is	used to generate a list of the columns in
       the specified  table  [table]  of  the  currenty  selected
       database.  If  the  _[_-_v_]  option is used the data type and
       length of the column are reported as well.  The	currently
       selected  database  is identified by the GRASS environment
       variable $PG_DBASE which  is  set  using  the  _g_._s_e_l_e_c_t_._p_g
       GRASS-RDBMS  interface  tool. If this environment variable
       is not set the program terminates with a  message  to  the
       user.  To  generate  a list of the available tables in the
       currently selected database use	the  command  _g_._t_a_b_l_e_._p_g.
       The  information  provided  by _g_._c_o_l_u_m_n_._p_g will be used in
       subsequent GRASS-RDBMS applications to formulate and  con-
       struct well formed database queries.
