-hackers is a list for discussion of development of PostgreSQL
itself. Your question would probably be more appropriate in -general
(which I am cc'ing) or perhaps -performance.
I believe EXPLAIN ANALYZE will provide what you're looking for. The
PostgreSQL documentation is a good place to get started:
http://www.postgresql.org/docs/8.2/interactive/sql-explain.htmlhttp://www.postgresql.org/docs/8.2/interactive/performance-tips.html
Hope this helps.
