Hi all, were trying to get slony 2.2.3 working between 2 nodes. 1 with 
postgres 9.3 installed. and another with 8.4. But we keep getting this error

<stdin>:506: PGRES_FATAL_ERROR load '$libdir/slony1_funcs.2.2.3'; - 
ERROR: could not access file "$libdir/slony1_funcs.2.2.3": No such file 
or directory
<stdin>:506: Error: the extension for the Slony-I C functions cannot be 
loaded in database 'dbname=tigris port=5432 host=192.168.2.59 user=postgres'

ive added the slon bin dir to my path but it still seems to have issues. 
any help would be great thanks!
