Like, I said uDig will load the layer. Quantum GIS with load and edit it.
Try Quantum GIS http://www.qgis.org/en/download.html

Thank you for your help Sean and Ralf.
When I load polygon table with srid of -1, Udig keeps saying undefined
spatial reference...unexpected behavior might occur...etc. And when I try
to edit the layer, the layer constantly flashing and Udig crashes.

I'm not sure why you want to assign it an SRS of EPSG:4326.
uDig will load and Quantum GIS will happily load and edit the layers if
you assign an SRID of -1.

A lot of these tools that connect to postigs db requires a srid. I was
trying out Udig. I don't need to use these tools. I can just work with
shapefile and import it to postgis.
But what I'm worry about is if I use a defined srid like EPSG:4326 and my
personal map coordinates will mess up because of the projection. The
world
I'm mapping is flat and endless, it doesn't wrap around like earth map.

Can you just set the SRID to -1. What 'map design tool' are you

I'm not mapping anything on earth. The world I'm doing is flat. The
polygons I'm drawing over is raster image I made. So I'm trying not to
use
any ellipsoid projection.

Do not use a local system. For everything larger than 200meters you
need a
srs definition, because you can't messure it exactly.
Take a projection from your living area und shift your geometrys to
the
right place.

Betreff: [postgis-users] Define spatial reference system for local
datum
I don't need special projection. My map is a flat plane so I'm trying
to
use local datum as my srs because a bunch of gis map design tool ask
for
it.
So I'm trying to add a new srs into postgis spatial_ref_sys table with
the
following srstext
LOCAL_CS["Non-Earth (Meter)",LOCAL_DATUM["Local
Datum",0],UNIT["Meter",
1],AXIS["X",EAST],AXIS["Y",NORTH]]
What do I put for proj4text?
