[mapserver-users] PostGIS problems in nightly

[Håvard Tveite]

I want to report a small problem I faced with a PostGIS
connection with the latest nightly build.

With the latest build I have problems with one of my
PostGIS connections.
The problem goes away when I switch back to the nightly
build from March 4th 2008.  Other PostGIS connections
seem to work fine on both builds.

The mapserver_log reports:

I am on Solaris 2.7

If I remove the trim statement ("trim(both ' ' from direction)
as direction"), and replace it with "direction" (untrimmed) there
is no error situation in the latest nightly.

Is this a bug?
