You can use something along that line:
CREATE SCHEMA new_schema;
ALTER TABLE table_name SET SCHEMA new_schema;
(either with pgdamin or with psql directly)
I personally find it easier to set the schema during the importation
step with shp2psql/raster2psql, e.g. using:
raster2pgsql -r your_raster.tif -t data.your_raster -l 1 -k 64x64 -s
26919 -I -M -o your_raster.sql
which will directly import 'your_raster' into the schema 'data'. I ran
into some problems with indexes by altering schemas*, and I now tend to
favour the direct import into the intended schema (and it's also quicker
as it involves less code).
Mathieu.
* After moving a given table in a different schema, I couldn't import
another table with the same name in the public schema because of the
associated index, and I add to merely drop the table. There is probably
a solution to this problem, but I couldn't find it and the drop was a
quick and easy solution for me...
