Trying to run the example slony config script in the documentation but
getting the following error:


postgres$ /tmp/slonik_example.sh
<stdin>:8: PGRES_FATAL_ERROR load '$libdir/slony1_funcs';  - ERROR:  could
not access file "$libdir/slony1_funcs": No such file or directory
<stdin>:8: Error: the extension for the Slony-I C functions cannot be loaded
in database 'dbname=my_primary host=localhost user=warfish
password=coalitions'

Yet the LIBDIR variable is set correctly:
postgres$ ./pg_config
BINDIR = /opt/local/lib/postgresql90/bin
DOCDIR = /opt/local/share/doc/postgresql
HTMLDIR = /opt/local/share/doc/postgresql
INCLUDEDIR = /opt/local/include/postgresql90
PKGINCLUDEDIR = /opt/local/include/postgresql90
INCLUDEDIR-SERVER = /opt/local/include/postgresql90/server
LIBDIR = /opt/local/lib/postgresql90

And the lib is present:

ls -l /opt/local/lib/postgresql90/slony1_funcs.so
-rwxr-xr-x  1 root  admin  34944 Feb 17 16:20
/opt/local/lib/postgresql90/slony1_funcs.so


Script is as follows:

cat /tmp/slonik_example.sh
#!/bin/sh

CLUSTERNAME=slony_example;
/opt/local/lib/postgresql90/bin/slonik <<_EOF_
define CLUSTERNAME slony_example;
cluster name = @CLUSTERNAME;
node 1 admin conninfo = 'dbname=my_primary host=localhost user=user1
password=pw'; 
node 2 admin conninfo = 'dbname=my_rep host=localhost user=user1
password=pw';
#-- 
# init the first node. Its id MUST be 1. This creates the schema #
_$CLUSTERNAME containing all replication system specific database # objects.
#-- 
init cluster ( id=1, comment='Master Node');
#--
# Slony-I organizes tables into sets. The smallest unit a node can #
subscribe is a set. The following commands create one set containing # all 4
pgbench tables. The master or origin of the set is node 1. 
#-- 
create set (id=1, origin=1, comment='All pgbench tables'); 
set add table (set id=1, origin=1, id=1, fully qualified
name='public.pgbench_accounts', comment='accounts table'); 
set add table (set id=1, origin=1, id=2, fully qualified
name='public.pgbench_branches', comment='branches table'); 
set add table (set id=1, origin=1, id=3, fully qualified
name='public.pgbench_tellers', comment='tellers table'); 
set add table (set id=1, origin=1, id=4, fully qualified
name='public.pgbench_history', comment='history table');
#-- 
# Create the second node (the slave) tell the 2 nodes how to connect to
Slony-I 2.1.1 Documentation 10 / 163
# each other and how they should listen for events.
#--
store node (id=2, comment = 'Slave node', event node=1);
store path (server = 1, client = 2, conninfo='dbname=my_primary
host=localhost user=user1 password=pw');
store path (server = 2, client = 1, conninfo='dbname=my_rep host=localhost
user=user1 password=pw');
_EOF_



Read in the doc that likely the lib is not in the correct place or $libdir
is not set correctly, but everything looks to be in place.  Am I missing
something else I am not aware of?
