I'm trying to create some tables on PostgreSQL with a Geometry field. For the Polygon and Point types it works but when I want to create a Line  o LSEG type I get an error.

If I do:

    .....
    geometry_field geometry(Polygon, 25829),

    or
    
    geometry_field geometry(Point, 25829),
    .....

it works and the table it's created but when I try:

    .....
    geometry_field geometry(Line, 25829),
    
    or
    
    geometry_field geometry(LSEG, 25829),
    .....

I get:

    ERROR:  Invalid geometry type modifier: line or lseg

Looking at the [Documentation][1] the type exists so I don't know what I'm doing wrong.

Where is my mistake? 

Regards.
