These are versions of dbSQL-tools for postgres database. The SQL-queries are transformed to postquel-form and the queries are made with the monitor program of postgres. The tools are tested with grass4.1, Postgres 4.1 and sunOS 4.1.1. You need the Postgres package of Berkeley university to run these programs. There is also a program which purpose is to link postgres and grass datastructure (called postgrass or something) , but I have nothing to do with that program. The purpose of these tools is to connect basic grass data with attribute data in Postgres. The original dbSQL-tools are made by J.A.Farley, W.Song and W.F.Limp from the University of Arkansas.
