I've just installed PostgreSQL yesterday and it ran fine with the exact same command:
pg_ctl -D /usr/local/pgsql/data start -l /usr/local/pgsql/log/pgsql.log
However, when I tried to run it again today, it didn't work, and I found the following message in the log file:
FATAL: unrecognized configuration parameter "default_text_search_config"
Can someone tell me what's wrong?
