Follow-up question, the locale setting on the host would still be set to en_US (as would the postgres and template0 databases). Should I look to change that locale on the system to en_US.UTF-8, or even just for the postgres user that the DB cluster runs as? What are the ramification for doing (or not doing) so?
One more question around the GUC settings for locale. It is currently set to this:
# select name,setting from pg_settings where name like 'lc%';
name | setting
-------------+---------
lc_collate | en_US
lc_ctype | en_US
lc_messages |
lc_monetary | C
lc_numeric | C
lc_time | C
Since I'm not changing the postgres or template0 databases (leaving those as en_US/LATIN1), do I keep lc_collate/lc_ctype as en_US? It's just the template1 and application database that I've set to en_US.UTF-8.
I'm also struggling to see how lc_messages is an empty string. It is commented out in postgresql.conf but suggests 'C' will be the default. The OS locale LC_MESSAGES is set to en_US on the primary but I also see it is set to en_US on the newer replica hosts. What value would be used for lc_messages? I'm trying to create an empty DB with these same settings but if I omit --lc-messages it uses the OS locale value, and I can't set it to an empty string.
