moving tablespaces

Hello.

I'm running postgresql 8.3.1 on Solaris 10.

I made a mistake when originally setting up the
database directory (which includes tablespaces). I
have moved it to a new location, and I have setup a
symbolic link that allows the db to find the
tablespaces. What I'm wondering about is how do I make
the change pernament in the database (ie. without
using symbolic links)?

What's the safe way to do that?

Is moving the symbolic links from pg_tblspc area
sufficient? DB needs to be shutdown for that. Will
that update the pg_tablespace table within the
database automatically?

Thanks,

Greg

Create a new tablespace and move the objects to it (alter table <foo>
tablespace ....). However this will be an exclusive lock for each object
as the task is performed.
