I cannot run my accounting software and have, I believe, isolated the problem by running 'psql' at the command line. When I run psql logged in as myself I get this error: [rshepard@salmo ~]$ psql aesi psql: error while loading shared libraries: libpq.so.5: cannot open shared object file: Permission denied Yet, when I su to user postgres and run the command it loads the shell: postgres@salmo:/home/rshepard$ psql aesi psql (9.0.1) Type "help" for help. aesi=# What directory or file has the incorrect ownership and/or permissions, and what should they be?
