[postgis-users] st_linetocurve problem

[Daniele Debernardi]

hi,
i have a problem with this square geometry

MULTILINESTRING((
     715476.865376701 92357.3121736097,
     715476.712298064 92356.8361831361,
     715477.188288538 92356.6831044996,
     715477.341367174 92357.1590949732,
     715476.865376701 92357.3121736097))

when i convert it with st_linetocurve i receive this geometry:

MULTICURVE(CIRCULARSTRING(
     715476.865376701 92357.3121736097,
     715477.188288538 92356.6831044996,
     715476.865376701 92357.3121736097))

with the first point equal to the last point.

is this a bug? how can i fix it?
