Hi Tom-san. This may be mere information...
In 8.3, when it has different encoding for every database, a locale requires C.

This user must also own the server process. The database cluster will be initialized with locale Japanese_Japan.20932. initdb: could not find suitable text search configuration for locale "Japanese_J apan.20932" The default text search configuration will be set to "simple". creating directory ../data ... ok creating subdirectories ... ok selecting default max_connections ... 100 selecting default shared_buffers/max_fsm_pages ... 32MB/204800 creating configuration files ... ok creating template1 database in ../data/base/1 ... ok initializing pg_authid ... ok initializing dependencies ... ok creating system views ... ok loading system objects' descriptions ... ok creating conversions ... ok creating dictionaries ... ok setting privileges on built-in objects ... ok creating information schema ... ok vacuuming database template1 ... ok copying template1 to template0 ... ok copying template1 to postgres ... ok WARNING: enabling "trust" authentication for local connections You can change this by editing pg_hba.conf or using the -A option the next time you run initdb.
