could not load library "/usr/lib/pgsql/xxid.so":
/usr/lib/pgsql/xxid.so: failed to map segment from
shared object: Permission denied

Function xxid.so is there in the /usr/lib/pgsql
directory stil its unable to load.

Can any one please help me which shared object it is
refering to...

Check permissions on the file. The postgres user will need to be able to
read it (at least) - not sure whether it needs to own the file but it
can't hurt..

Thanks Chris ,
I ahve checked the permissions on the xxid.so file and
it ids having all permission i.e. 0777
I think its not getting the permission from the object
which xxid.so is refering, any idea which object it is
refering....

Are you running SeLinux by any chance? That could be an issue..

or maybe try:

ldd xxid.so

to see what xxid.so is trying to use.

I am using Redhat Linux 4
Now the problem is solved.I installed Postgres 8.1.5
from source code previously it was installed using rpm
on slave machine.

but then i am having one problem :
I am left with following details
I am having two machine

1)Master machine :
Redhat linux
PostgreSQL 8.1.5 -- installed using RPM
Slony 1.2.1---installed using Source code

1)Slave machine :
Redhat linux
PostgreSQL 8.1.5 -- installed using source code
Slony 1.2.1---installed using Source code.

Its running fine now. but will there be any problem in
future as the master and slave PostgreSQL server are
installed using diffrent pacakage i.e. master with RPM
and slave with source code?

I know this is not the solution but for time being its
working fine.

also could you please suggest me if I installed
PostgreSQL with RPM on redhat Linux then which object
was that xxid.so (failed to map segemnt from shared
object -permission denied)function was refering ?
