DDEESSCCRRIIPPTTIIOONN
       _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 avail-
       able 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 subse-
       quent GRASS-RDBMS applications to formulate and construct  well	formed
       database queries.
