<DIV><FONT face=Arial size=2>Dear list,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have troubles to get PostGIS to work with
MapServer.</FONT></DIV>
<DIV><FONT face=Arial size=2>I went through the PostGIS tutorial, using the
sampe data. PostGIS works great on the command line.</FONT></DIV>
<DIV><FONT face=Arial size=2>But then I tried to call PostGIS with the MapServer
as described in the tutorial adding the following layer to the map file of some
working sample maps of nboth GMap and Chameleon:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV><FONT face=Arial size=2>
<DIV>LAYER<BR> NAME "elections"<BR> CONNECTIONTYPE postgis<BR>
CONNECTION "host=localhost port=5432 dbname=bc password=[ I won't tell you! :-)
] user=postgres"<BR> DATA "the_geom from
bc_voting_areas"<BR> TYPE
POLYGON<BR> STATUS OFF<BR>
PROJECTION<BR> "proj=aea"<BR>
"ellps=GRS80"<BR> "lon_0=-126"<BR>
"lat_0=45"<BR> "lat_1=50"<BR>
"lat_2=58.5"<BR> "x_0=1000000"<BR> END<BR>
CLASS<BR> NAME "Voting Areas"<BR>
OUTLINECOLOR 0 0 0<BR> COLOR 255 255 200<BR>
END<BR>END</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>If the layer is disabled (STATUS OFF) then everything is OK. BUT if i
enable it, MapServer cannot render the map (image missing symbol in the
browser). I switched on the Apache error logging to see what happens. Here is an
extract of the error log. A column oid seems to be missing... But that does not
make me smarter. I got similar error logs with both GMap and
Chameleon.</FONT></DIV>

<DIV><FONT face=Arial size=2>I am quite deseperate: I tried different versions
of MS4W (1.0.3 and 1.2.2) but that did not change the situation.</FONT></DIV>
<DIV><FONT face=Arial size=2>I am using PostgreSQL 8.1 with the PostGIS included
with it under Windows XP Pro SP2.</FONT></DIV>
<DIV><FONT face=Arial size=2>Trying step by step different PostGIS tutorials I
get the same error.</FONT></DIV>
<DIV><FONT face=Arial size=2>I have tried this on 2 different computers and get
the same errors.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>What can be the problem? As opposed to what I have
read in the forum, in my situation ALL layers die when I try to get a layer via
PostGIS.</FONT></DIV>
<DIV><FONT face=Arial size=2>I previously used MySQL via ODBC but that gave me
trouble as well (I could not query the database, just dump a complete column).
This is why I decided to convert to PostGIS (which is MUCH better anyway for my
task).</FONT></DIV>
