Global Default Locale Configuration for PostgreSQL Databases

[oyale]

Hello,

This Pull Request introduces a refinement to the Ensure PostgreSQL databases are present task, providing an option for setting a global default locale. While the existing role does permit locale modification at the individual database level, I observed that there are use cases where one might need to change the default locale across all databases without having to specify lc_collate and lc_ctype for each one. This led me to propose this enhancement.

The following lines in databases.yml have been updated to use the new postgresql_default_locale variable when individual lc_collate and lc_ctype values are not provided:

lc_collate: "{{ item.lc_collate | default(postgresql_default_locale) }}"
lc_ctype: "{{ item.lc_ctype | default(postgresql_default_locale) }}"

I have added the postgresql_default_locale variable to the defaults/main.yml file. This new variable allows users to define a global default locale:

postgresql_default_locale: 'en_US.UTF-8'

Additionally, I have updated the README to explain the purpose of this new variable and how to use it. The documentation clarifies that postgresql_default_locale is used to set default lc_collate and lc_ctype values for all databases, unless specifically overridden for a particular database.

This modification aims to increase the role's versatility and simplify PostgreSQL database configuration by offering a global default locale setting.

I look forward to hearing your thoughts on this proposed change.

Thank you.
