Changing Language in taxonomy causes error in Postgres

With i18n active when I set the language for a Vocabulary I get and error on postgres.

query: UPDATE term_data t SET t.language='en' WHERE t.vid=1 in /var/drupal/includes/database.pgsql.inc on line 113.

I found the query is in i18n/i18n.inc line 218:

db_query("UPDATE {term_data} t SET t.language='%s' WHERE t.vid=%d", $edit['language'], $edit['vid']);

I changed it for (and it works):

db_query("UPDATE {term_data} SET language='%s' WHERE vid=%d", $edit['language'], $edit['vid']);

I don't believe the t alias is really needed, it breaks on Postgres.
