Usage

pg_xenophile: internationalization (i18n) and localization (l10n) utilities

The pg_xenophile extension provides i18n/l10n infrastructure including reference data for countries, languages, and currencies, plus automated localization table management.

CREATE EXTENSION pg_xenophile CASCADE;

All objects reside in the xeno schema (non-relocatable).

Reference Tables

• xeno.country: ISO 3166-1 codes with calling codes and currencies
• xeno.lang: ISO 639-1 language codes
• xeno.currency: ISO 4217 currency codes with symbols
• xeno.country_subdivision: ISO 3166-2 subdivision codes
• xeno.eu_country: EU membership tracking
• xeno.country_postal_code_pattern: Postal code validation patterns

Localization Tables

The extension auto-manages translation tables. Insert into xeno.l10n_table to register a translatable base table:

INSERT INTO xeno.l10n_table (base_table_schema, base_table_name)
VALUES ('public', 'products');

This automatically creates a companion products_l10n table and language-specific views.

Convenience Views

• xeno.country_l10n_en: Country names in English
• xeno.lang_l10n_en: Language names in English
• xeno.country_subdivision_l10n_en: Subdivision names in English

Configuration

SET pg_xenophile.base_lang_code = 'en';
SET pg_xenophile.user_lang_code = 'en';
SET pg_xenophile.target_lang_codes = '{nl,fr,de}';
