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.
