Default text_serach_config

Hello,

I am building a test instance of PosgreSQL 8.3.6 on a Solaris 10 box.
When start the server, if fails to start.  In the log there are these
statements...

-bash-3.00$ more data836.log
FATAL:  unrecognized configuration parameter
"default_text_search_config"
FATAL:  unrecognized configuration parameter
"default_text_search_config"
-bash-3.00$

I saw no default_text_search_config in the configure file.  I didn't
change the one in postgresql.conf.  It still says pg_catalog.english.

Thanks,
Carol
