World: r3wp

It comes on CREATE Table as well as SQL without table references 
in it ... e.g. simple SELECT

The error message seems to be the problem ... the table is CREATEd 
and is usable from new rebol sessions which load the protocol fresh.

Thanks Doc.  I can work around that TABLE message using the pgAdmin. 
 The Send-SQL and /FLAT protocol updates work exactly the same as 
on MySQL for me.

Glad to hear that.

The cause of the error above is a communication protocol change, 
the driver was made for 7.x. It would need a good upgrade.
