The context here was a new feature in PgAdmin, which needs to be able to
parse the SQL *and* find out the schema of a table.
The idea was to have a tool that would issue an EXPLAIN *and* collect
all the other relevant details required to submit an optimizer question
to the lists. The tool would then be able to check for simple things
like not having run ANALYZE.
That feature would be very useful in identifying optimizer issues, as
well as filtering out many requests that arrive, only to be easily
explainable. Greg's small patch will allow this useful utility to be
available for use with the 8.3 release package, so I hope you'll
reconsider.
Of course, XML output can be done for the next release.
