[postgis-devel] [postgis-users] Has anyone seen this before?

[Paragon Corporation]

Haven't finished analyzing the situation yet, but don't think its bad RAM as
I had originally suspected.

The reason is as follows
1) If I take this original good table -- restore it on a PostGIS 1.4
database on the same server and repeat the copy process, it works fine.

2) Restoring it on their production server (different server), which is a
1.3.6 and then repeating the process gives the same problem.

This database is a backup of their production database, so could be some
corruption in the original production.

So next step is to create a clean 1.3.6 database on this dev server and
repeat the process to rule out 1.3.6 as the culprit.  Hope to get around to
doing that sometime today.

Thanks,
Regina

For only my own benefit possibly, but is this because the geometry column is
being stored outside the normal table pages (the TOAST bit)?

cheers
