Thread: ERROR: bogus varno: 1 with 8.1beta and postgis 1.0.3

ERROR: bogus varno: 1 with 8.1beta and postgis 1.0.3

With psql 8.1beta1 I get a pretty cryptic error message "ERROR: bogus varno: 1"
occasionally when I try to mix postgis (GIST-based) conditions with normal
conditions.  The statements where this happen are totally reroducable.

Attached is an example of this happening.   I'd be happy to look further,
but I'm not really sure where to look myself; and I must apologize in 
advance that I'll be traveling for a couple days so my response time 
for getting more info may be slow.  I'm using the latest postgis and the
beta of 8.1 on ubuntu.  The previous postgis claims to have some support 
for 8.1 added; and quite a few statements seem to work fine.

Any thoughts where I should look next?

Thanks for detailed report. However, others beat you to it. Tom fixed the
problem on the weekend.
