Re: LATIN2 encoding and Polish_Poland locale

Hello Andrzej,

try this:

Identify the code page Windows is using for LATIN2 with the PostgreSQL tool pg_controldata (8.2 server's version). Look for the number following the dot in LC_COLLATE / LC_TYPE. For LATIN1 it's 28591.

Try creating the database for 8.4 with the PostgreSQL tool createdb (v8.4.x) (example for LATIN1 and German locale, locale = LC_COLLATE / LC_TYPE in 8.2):

createdb -U postgres -h <Host> -p <Port> --owner=name_of_owner --locale=German_Germany.28591 --encoding=LATIN1 --template=template0 database_name

Good luck,

Peter
