How to show lines between PostGIS data of type POINT

[Sebastian Albrecht]

Hello,

is it possible to show lines between POINT data results from a
PostGIS-DB? Is it possible to somehow convert one point and the next
one following to a line on-the-fly each time the Mapserver queries the
database?

My problem is I have a lot of single latlon points which have
different timestamps and further values. The user should be able to
query these values of a single point but lines should be shown in the
map. Using a LINE type would not be very consistent because the user
would not know which end of the line is the point the values belong
to.

One knows something? ;)

Best regards,
Sebastian
