restoring a shadow

In my  attempts of  trying to increase  performance and  redundancy, I
have trying to get rServ replication to work.

I have  successfully been able  to replicate between two  databases on
localhost.
       test            -> Main db       test_slave      -> Slave db

The 'test'  database is  located in PGDATA  (/var/lib/pgsql/data), and
'test_slave' in  PGDATA2 (/var/lib/pgsql/data2). Works  fine (although
I'm a little unhappy about the replication speed).

Now, I'd  like to have  PGDATA in a  ram disk (we're only  expecting a
maximum of  10-15Mb of data). The  problem is if the  machine is being
reset  (hardware  vice)  or if  it  crashes.   Then  the ram  disk  is
lost. This is where PGDATA2 comes into play...

I've  been   experimenting  with  renitialize   the  PGDATA  directory
structure, and doing a
       insert into pg_database values       ('test_slave', 26, 0, 'f', 't', 18539, 'PGDATA2');

Also, a  link from  PGDATA2/base/709432 -> PGDATA/base/709432  is made
(this is what the 'original' PGDATA directory/pg_database table have).

Unfortunatly this give me:

FATAL 1:  Database "test_slave" does not exist.         The database subdirectory '/var/lib/pgsql/data/base/18720' is
missing.
