[postgis-users] Problem in using Postgis 2.0.0b3 with raster

[Mathieu Basille]

Here is a possibility (which is what I do):

1) for the sake of convenience, create symlinks in /usr/local/bin/ as a root:

# ln -s /usr/lib/postgresql/8.4/bin/shp2pgsql /usr/local/bin/shp2pgsql
# ln -s /usr/lib/postgresql/8.4/bin/raster2pgsql /usr/local/bin/raster2pgsql
# ln -s /usr/lib/postgresql/8.4/bin/pgsql2shp /usr/local/bin/pgsql2shp

It will allow you to call the 3 commands from any folder.

2) Create a new data base user, as postgres root:

# su postgres
# psql -d template1 -c "ALTER USER dbuser WITH PASSWORD 'dbpwd'"

3) If you want to be able to use the db without the need to type passwords 
(very handy to script things), you can create a file .pgpass in your home, 
with just this line:

localhost:5432:*:dbuser:dbpwd

And then give it the minimum permissions:

chmod 600 .pgpass

4) Now test the connection, from any user:

psql -h localhost -d yourdb -U dbuser -c 'SELECT current_date;'

This should work! If you don't want to use step 3 (no password), just add a 
-W in the command, if I'm not mistaken.

Hope this helps,
Mathieu.
