pg_dump and money type

Since the money type has a locale dependent input and output format, there has
to be some context saved when a database dump is created. For example, if
your environment uses a locale that uses the opposite point-vs-comma
conventions from English (e.g., de_DE), then the following will fail to
replicate the regression test database:

pg_dump regression | psql foo

The database regression has lc_monetary = C set, so this will produce C output
piped into, say, de_DE input.

The first problem appears to be that pg_dump --create ought to save the
database-specific configuration settings. pg_dumpall gets this right. But
secondly, lc_monetary ought to be saved at the top of the dump file, much
like client_encoding. Unfortunately, that would probably break portability
of dump files between different operating systems. Perhaps we can get away
with fixing --create and documenting this. But something ought to be done
about this; otherwise using the money type introduces a risk of breaking
backup or upgrade procedures.
