I would like to see PostgreSQL eventually support XQuery:


I see potentially an alternative front end called xsql, providing
substantially the same functionality as psql, only using XQuery syntax and
optionally returning recordsets as XML.

Anybody want to put together a team to explore this seriously? There are
probably several non-trivial semantic issues on the back end, but I only
dimly grasp them at this point.
