Re: upgrade from FC9 / PG8.3 to C7 / PG 9.6 - utf8

So long as you use pg_dump from PG 9 to dump the PG 8 databases, you'll be fine.

en_GB.UTF-8 will be fine (and is probably preferred).

Subject: upgrade from FC9 / PG8.3 to C7 / PG 9.6 - utf8

I'm performing a long overdue upgrade of a Fedora 9 / Postgresql 8.3 to a
Centos 7 / Postgresql 9.6 system.

I'm just going though the config files to check that everything is okay and
I've found a discrepency regarding language settings. I realise things have
progressed a lot since 2008 when I built this server, so I wonder what is the
right thing to do moving forward. The old system has

# These settings are initialized by initdb, but they can be changed.
lc_messages = 'en_GB' # locale for system error message strings
lc_monetary = 'en_GB' # locale for monetary formatting
lc_numeric = 'en_GB' # locale for number formatting
lc_time = 'en_GB' # locale for time formatting

while the new system has

lc_messages = 'en_GB.UTF-8' # locale for system error message strings
lc_monetary = 'en_GB.UTF-8' # locale for monetary formatting
lc_numeric = 'en_GB.UTF-8' # locale for number formatting
lc_time = 'en_GB.UTF-8' # locale for time formatting

Am I best changing the new system to match the old one?
If I leave the settings as they are, enabling the utf-8, how will it affect
a) the pg_dumpall / pg_recover process
b) using the database moving forward?
