ODBC with Visio - what's wrong with my connection string?

I'm attempting to link VISIO shapes to my PostgreSQL database. I'm
linking the properties of the shape to columns in a view. Visio sends
an ODBC request, but all that is returned is:

parser error at or near "."

Here is what visio is sending to map the requests to the properties of
the Visio shape:

="ODBCDataSource=PostgreSQL-csc2426|ODBCQualifier=ODBCDataSource=PostgreSQL-csc2426|ODBCTable=roadmapview|3|activityid=Prop.activityid|acode=Prop.acode|ccode=Prop.ccode|57|actor1=Prop.actor1=0|actor10=Prop.actor10=0|actor2=Prop.actor2=0|actor3=Prop.actor3=0|actor4=Prop.actor4=0|actor5=Prop.actor5=0|actor6=Prop.actor6=0|actor7=Prop.actor7=0|actor8=Prop.actor8=0|actor9=Prop.actor9=0|aname=Prop.aname=0|as1=Prop.as1=0|as2=Prop.as2=0|as3=Prop.as3=0|as4=Prop.as4=0|as5=Prop.as5=0|cname=Prop.cname=0|functionalrole1=Prop.functionalrole1=0|functionalrole10=Prop.functionalrole10=0|functionalrole2=Prop.functionalrole2=0|functionalrole3=Prop.functionalrole3=0|functionalrole4=Prop.functionalrole4=0|functionalrole5=Prop.functionalrole5=0|functionalrole6=Prop.functionalrole6=0|functionalrole7=Prop.functionalrole7=0|functionalrole8=Prop.functionalrole8=0|functionalrole9=Prop.functionalrole9=0|ots1=Prop.ots1=0|ots10=Prop.ots10=0|ots2=Prop.ots2=0|ots3=Prop.ots3=0|ots4=Prop.ots4=0|ots5=Prop.ots!

Obviously PostgreSQL doesn't like the .'s. I'm fairly sure I won't be
able to change the formatting of the properties in Visio to eliminate
the .'s - any ideas on how the request can be sent witout PostgreSQL
complaining?
