This task is only executed when the playbook has already been executed
once, for example using 'ansible-test integration' with '--retry-error'
switch when the first run fails.
This modification allows to recreate default databases (postgres,
template0 and template1) using the same encoding that the one used by
the Debian package.
Default encoding is 'SQL_ASCII' when default locale is not set in
/etc/default/locale.
/usr/sbin/locale-gen differs between Debian and Ubuntu. With Debian,
locales must be added to /etc/locale.gen before calling locale-gen
command. With Ubuntu, /etc/locale.gen is updated by
/usr/sbin/locale-gen.
Use the locale-gen module which handles both distributions.
