<DIV>fortunately I have linestring version of the polygon, but it seems that the linestirings are not continuous. Does st_distance still apply? Or are there any postgis function to make the polyline continuous?</DIV>

<DIV align=left>Hallo</DIV>

<DIV align=left>I think the easiest way is to make a linestring of the polygon.boundary and then cut the line in the start and end so you get two more or less paralell lines.. Then you can use st_distance to find the shortest distance between them.</DIV>

<DIV align=left>Hope that helps</DIV>

<DIV>I have a river polygon with polygon length about 20 km. How can I query the minimum width of the river polygon. I tried to search previous threads, but I could not find any clue.</DIV>
