[GRASS5] Can't get d.vect to display my data from PostGRASS

[Funkmeister]

Opps, this message may get posted twice - i apologize!


Hello Grass Developers. I am using GRASS 5.7 with PostGIS. I have
converted an e00 file using  avcimport
(http://avce00.maptools.org/avce00/) and imported the files into
PostGRASS server.

The file is very large, however I can only see one polygon. There should
be 1000's. I pushed up the debugging level and some of the (hopefully)
relevant output is below:

The log file is 11Mb, so here is a snippet:
<snip>
D1/3: display areas:
D2/3: n_areas = 0
D1/3: Vect_Rewind(): name = bntl_bc
D3/3: Vect_read_line()
D3/3: V2_read_line_post(): line = 1
D3/3: Vect__Read_line_post(): id = 301
D3/3: select type, NumPoints(geom) , Dimension(geom)  FROM  bntl_bc_geom
where id  = 301;
D3/3:   store type = 2 n_points = 7
D3/3: DECLARE gcursor BINARY CURSOR FOR SELECT ASBINARY(
force_2d(geom),  'xdr')  FROM bntl_bc_geom WHERE id = 301
D3/3: FETCH ALL in gcursor
D3/3: wkb length = 121
D3/3: np = 2
D3/3: np = 2
D3/3: SELECT field, cat FROM bntl_bc_cat WHERE id = 301;
D3/3:   gType = 2 -> type = 2
D3/3: Vect_read_line()
D3/3: V2_read_line_post(): line = 2
D3/3: Vect__Read_line_post(): id = 301
D3/3: select type, NumPoints(geom) , Dimension(geom)  FROM  bntl_bc_geom
where id  = 301;
D3/3:   store type = 2 n_points = 7
D3/3: DECLARE gcursor BINARY CURSOR FOR SELECT ASBINARY(
force_2d(geom),  'xdr')  FROM bntl_bc_geom WHERE id = 301
D3/3: FETCH ALL in gcursor
D3/3: wkb length = 121
D3/3: np = 2
D3/3: np = 2
D3/3: SELECT field, cat FROM bntl_bc_cat WHERE id = 301;
D3/3:   gType = 2 -> type = 2
D3/3: Vect_read_line()
D3/3: V2_read_line_post(): line = 3
D3/3: Vect__Read_line_post(): id = 301
D3/3: select type, NumPoints(geom) , Dimension(geom)  FROM  bntl_bc_geom
where id  = 301;
D3/3:   store type = 2 n_points = 7
D3/3: DECLARE gcursor BINARY CURSOR FOR SELECT ASBINARY(
force_2d(geom),  'xdr')  FROM bntl_bc_geom WHERE id = 301
D3/3: FETCH ALL in gcursor
D3/3: wkb length = 121

Note the id=301.

What is that and where does it come from? I did not specify that
anywhere in a query, and I suspect that is why I only get one polygon. I
am a novice with PostGIS, but I took a look at id=301 in Postgres in the
table bntl_bc_geom and this is what is there:

    301 |    2 | SRID=-1;LINESTRING(1551506.75 505591.8125,1558783.5
506437.65625,1566056.5 507288.3125,1564843.5 518251.875,1557581.875
517397.5625,1550317.125 516547.34375,1551506.75 505591.8125)

In total there is 17185 rows in the table.


Also...I have imported other e00 files that have less than 300 lines of
data in the tables. d.vect crashes with a bus error. When I try to
display a subset of the data using d.vect I get warning messages:
"WARNING: Cannot select line 301 from database"

So where does the 301 come from, and how can I get rid of it?

Thanx in advance,
Craig
