no usable system locales were found - Alpine postgres

[bharanitharanm]

Getting this error during postgres startup,

sh: locale: not found
2025-01-30 10:33:25.556 UTC [36] WARNING:  no usable system locales were found

I dont see any issues beacuse of this. Databases are created with en-US ICU locale,

Need to understand if there is anything needs to be configure to avoid this error. Also are there any impact because of this error?

Currently I'm using, postgres:16.6-alpine3.20

I tried setting this environment variable, still it is not resolved,

POSTGRES_INITDB_ARGS: --locale-provider=icu --icu-locale=en-US
