some people might remember the Sequoia 2000 project. That
time an interface GRASS-Postgres was written. The last years
it was quite calm, but now we present the new
PostGRASS project: GRASS gets an interface to PostgreSQL
by Carl Anderson <candrsn@mindspring.com>
Background: GRASS still lacks of a powerful interface
to (free) database management systems. PostgreSQL
(www.postgresql.org) is such an DBMS. PostGRASS shall
be GRASS with an interface to this DBMS for direct
accessing postgres data through GRASS modules
(currently available: d.site.pg, d.vect.pg, g.select.pg,
g.table.pg, d.what.s.pg).
We hope to find more people interested in extending this
interface!
Markus Neteler, is a bit over anxious for PostGRASS.
The project to interfaces Postgress and GRASS is ongoing and some
working modules do exist. But the code needs testing, some general interface
questions are being resolved, and other people are working on the interface.
What has been posted (as of 11/15) for user testing:
d.site.pg
d.vect.pg
d.what.s.pg
g.column.pg
g.select.pg
g.stats.pg
g.table.pg
text_functions.sql - needed for g.stats.pg
- should be in system functions but alas....
These modules are modifications to the Postgres / GRASS code offered by Markus
in September.
The posted modules are strictly for category support of GRASS datasets.
As such, I propose renaming the modules as follows (to make room for proper
spatial support):

I am also supportive of the proposed name changes for the
postgresql- GRASS interface modules. I am glad to see that there has been
continued interest in the linking of these two wonderful softwares.
Which version of Postgresql has the recent work with interface been done?

Hi, all
I have compiled the postgrass on linux RH5.1.
But it have Error Message: PG_HOST not set when I run g.select.pg or
g.table.pg ...
PG_HOST xxx.xxx.xxx.xxx or setenv PG_HOST pg_path both don't work.
How I should to set PG_HOST ??
BTW, I have change linux from Slackware to RH.
I used gmake4.2 to compile sources very well on Slackware, but
it seem be many errors after I install RH.
for examples:
OBJ.linux/label.o(.text+0x10b):the `gets' function is dangerous and
should not be used.
What's wrong?
Thanks for your help
