- * From: "Martin J. Laubach" <mjl@CSlab.tuwien.ac.at>
- * Subject: [HACKERS] Patch: set date to euro/us postgres/iso/sql
- *
- *   Here a patch that implements a SET date for use by the datetime
- * stuff. The syntax is
- *
- *         SET date TO 'val[,val,...]'
- *
- *   where val is us (us dates), euro (european dates), postgres,
- * iso or sql.
- *
- *   Thomas is working on the integration in his datetime module.
- * I just needed to get the patch out before it went stale :)
