Re: Setting "ucs_basic" as the default database collation

CREATE DATABASE wants you to specify a locale, which ucs_basic is not.
It's defined by SQL as a standard collation name, but that doesn't
make it a complete locale specification. You can do something like

regression=# create database db1 with encoding = 'utf8' locale = 'en_US.utf8' template = template0;
CREATE DATABASE

or

regression=# create database db2 with encoding = 'utf8' icu_locale = 'en-US-x-icu' locale_provider = icu template = template0;
CREATE DATABASE

or

regression=# create database db3 with encoding = 'utf8' locale = 'POSIX' template = template0;
CREATE DATABASE
