Re: Restore Windows dump to Linux (locale issue)

If the dump file is too big to edit conventionally, piping it through a stream editor like sed to make the required changes works nicely.
It can be done on the fly in the restore process if required.

Edit the dump so that the databases are created with Linux-compatible
locale names. You should find lines like

CREATE DATABASE foo WITH TEMPLATE = template0 ENCODING = 'UTF-8' LOCALE_PROVIDER = libc LOCALE = 'tr-TR';

(details will vary depending on PG version) and changing the locale
strings ought to do the trick.

If the dump file is too big for your editor, consider splitting it
into schema-only and data-only dumps.
