[postgis-users] transform to postgis

[pinktomate]

if I have a table with coordinates gauss

for example

station         easting         norting
1               1000000         1000000 
2               2000000         2000000
3               3000000         4000000
4               4000000         5000000


in text tabulated, how to transform this table in a shapefile with
spatial component, (spatial points) to introduce it in postgis

is very important for me, 

I want to do the same operation in arcview add event theme, but in
linux, without arcview, 

regards and please help me
