Yes. Here's what you need to do:
first, go to the postgresql-7.x.x/contrib/oid2name directory (as root) and
do a make;make install so you have the oid2name utility installed.
then, do:
oid2name | grep dbname
where dbname is the name of the database you want to move an index around
on. You should get a line like 10964230 = dbname back..
As the postgres superuser, do:
cd $PGDATA/base/oidfromoid2nameabove (i.e. 10964230 in my example)
Next do:
oid2name -d dbname|grep indexname
to get the oid of the index.
Then, shutdown the server and cp your index elsewhere:
pg_ctl stop
cp 10965165 /mnt/indexdisk/10965165
rm 10965165
ln -s /mnt/indexdisk/10965165
pg_ctl start
And that's that.
