This is in no way a PostGIS problem, certainly nothing we can ever
fix, just something that the particular combination of PgAdmin, the
geometry we are feeding it, and the way the Windows rendering system
are interacting.
My experience has been that these days the thing that causes a modern

This is a well-chewed issue, and we have come down repeatedly in
favour of allowing invalid geometry to be loaded. Which, I suppose,
means we should loosen the parser to allow even non-closed rings.
What *does* need to be done (issue for me, it's not that hard) is a
few additional hooks to the

Mark, is there any chance of you posting your datasets for experimentation
purposes?

What GEOS are you using, Bill? Your PostGIS is mismatched to the GEOS.
Or, at least, *something* is mismatched. Do you have old GEOS libs
hanging around? Old postgis libs? Try really reaming out the system
and ensure that the only things around are your new fresh builds.

Please file in the issue tracker.
Even better, submit a patch: this isn't something that takes anything

If you have control of both the pgsql and the sde, you could use

Is that the only function of the buffer - to create a circle?
Can the buffer modify other functions. If so - what is the criteria?
