Note: this is for old Postgres installs that lack the
|
|
pg_import_system_collations function.
|
|
|
|
We need to operate as user so that the new collation has the proper
|
|
ownership. We connect to template1, because by default we can't connect
|
|
to template0.
|
|
|
|
$ sudo -u postgres psql -d template1
|
|
|
|
Now allow ourselves to connect to template0
|
|
|
|
template1=# UPDATE pg_database SET datallowconn = TRUE WHERE datname = 'template0';
|
|
template1=# \c template0
|
|
|
|
Create collation in the proper schema (pg_catalog). Quote collation name
|
|
to preserve capitalization.
|
|
|
|
template0=# CREATE COLLATION pg_catalog."en_US" (LOCALE='en_US.utf8');
|
|
|
|
Now reset datallowconn to FALSE.
|
|
|
|
template0=# UPDATE pg_database SET datallowconn = FALSE WHERE datname = 'template0';
|
|
|
|
Now any database created from the template0 template will inherit the new
|
|
collation.
