[postgis-users] Closing a LINESTRING

[James G Wilkinson]

I am not sure this is the correct board for this, but here goes.

I have a GEOMETRYCOLLECTION that represents a
meandering line.  It is a valid geometry per ISVALID(), and
it is not closed per ISCLOSED().  Is there anyway that I
can insert an additional line into this collection so that ISCLOSED()
will return true?  That is I want to connect the start point and end
point of this collection.

Regards,

Jim
