Taking off from this table:
table cutlery_types
id description
----------------
1 Spoon
2 Fork
3 Knife
4 Teaspoon
you might use a table set like this:
table lg_dependent
oid_table | column | id_row | language | text
---------------------------------------------------
######### | desc | 1 | en | Spoon
######### | desc | 1 | ger | Löffel
######### | desc | 1 | fr | Cuilliere
######### | desc | 1 | el | Koutali
Use a select statement like this:
select t1.id, t2.text /*, etc */
from cutlery_description t1
join lg_dependent t2 on t2.oid_table = (select oid from pg_class where
relname='cutlery_types') and t2.column='desc' and t2.language='en'
It might be better to _not_ use the table oid to be more portable across
databases, or pg_dumps without OID. You might either use the table name
then, or have another table mapping table names to unique numbers.
