Before configuring Postgres Pro for 1C solutions, make sure that the Russian locale is installed on the system and that it is the active locale of the user who creates the database cluster. The following example shows how to set up the ru_RU.UTF-8 locale for Debian systems:

sudo dpkg-reconfigure locales
export LANG="ru_RU.UTF-8"
/opt/pgpro/std-15/bin/pg-setup initdb

For more details, see related documentation sections for your operating system and for 1C.
