Hi,

Can anyone tell me how pg_analyze_and_rewrite
works?

That's a rather broad question.  Have you read the overview in the manual?
    http://developer.postgresql.org/pgdocs/postgres/overview.html
pg_analyze_and_rewrite covers what that material calls the
"transformation process" and "query rewrite" stages of processing.

If you've got specific questions about pieces of that code,
pgsql-hackers is probably a better place than -general for asking 'em.
