Moving database and schema to a new tablespace

Hi,

I'm looking to move a database by using ALTER DATABASE $DB  SET TABLESPACE and i'd also like to move a schema over to
thesame new tablespace, googling around, it looks like there was a an ALTER SCHEMA $SCHEMA SET TABLESPACE command in
thepast, but apparently no longer.   I'm using Postgres 9, can anyone confirm if this is still possible, and if not,
howI can move the schema over ? 

Thanks in advance

Richard

ALTER SCHEMA... SET TABLESPACE never existed in PostgreSQL.

As you're using PostgreSQL 9, you can use the DO command to do something
like this. You need to find every table in the schema, and launch ALTER
TABLE... SET TABLESPACE to them. And then do the same with indexes.
