That's because of the changes in 9.1 to determine client_encoding
automatically from the system locale (commit 02e14562). Unless
PGCLIENTENCODING environment variable is set, psql adds
client_encoding='auto' to the params it passes to PQconnectdbParams.
That overrides any setting you manually pass in the backend command-line
options.
That doesn't seem desirable, actually. That could be changed easily, by
passing the client_encoding='auto' setting *before* dbname in the
PQconnectdbParams call. The options given by the user are parsed from
dbname setting, so if we passed them in different order, the manually
given options would override the client_encoding='auto' setting, not the
other way round. That seems like better behavior. Patch attached. It
might be better to not backpatch this, though, to avoid surprising and
subtle changes in behavior in application.
