I have a C-language function I've been using on 8.4 for a long time. On 9.2 it won't load:
test=# set search_path = public;
SET
test=# CREATE OR REPLACE FUNCTION chmoogle_session_id() RETURNS integer
AS '/usr/local/pgsql/lib/libchmoogle.so', 'chmoogle_session_id'
LANGUAGE c VOLATILE;
ERROR: could not load library "/usr/local/pgsql/lib/libchmoogle.so": libopenbabel.so.4: cannot open shared object file: No such file or directory
But libopenbabel.so.4 does exist:
# ls -l /usr/local/pgsql/lib/libopenbabel.so.4
-rwxr-xr-x 1 root root 18250709 2012-10-09 18:05 /usr/local/pgsql/lib/libopenbabel.so.4*
There seems to be some difference in the library search path from 8.4 to 9.2. For administrative simplicity, I don't use ldconfig, besides which it wasn't needed for 8.4.
What changed in how libraries are loaded between 8.4 and 9.2?
Thanks,
Craig
