[PATCH] Support for geometric types in pg_convert()

Hello,

I've put together a patch[1] for pg_convert() that adds support for
PostgreSQL's geometric types (point, line, box, path, polygon and circle).
I couldn't find any bugs open for this, so I figured I should just send it
in. It also fixes some issues with the regexs for interval types I wrote
in a previous patch. If someone could review the patch and commit it, it
would be much appreciated. The patch is against CVS HEAD.

Thanks,

Benj Carson
