PostgreSQL version: 8.3.0
Operating system: Linux
Description: pg_ctl assumes that all config files lie in
data_directory
Details:
pg_ctl doesn't work if you put postgresql.conf in a different directory than
the database data files. According to the documentation, this is however
considered a good practice:
