The issue here has to do with what you called your geometry column in
the database. If you loaded the data using shp2pgsql and did not specify
a geometry column name then the default is "the_geom" and not "geom"
If you are not sure then check with psql like
psql -U postgres -h localhost delhiroads
\d asia_southern_asia_india_delhi_highway
\q
And look for the column name for the geometry type column. If you used
mixed case names then you need to double quote the column names of the
connection will fold the names to lowercase and you will not find the
column.
