Hi!
I am an Oracle DBA in need of PgSQL documentation. Where can I find the
documentation describing:

1) PostgreSQL data and index block formats
2) The entrails ("inner workings") of PgSQL locking mechanism
3) Statistics collection process and its options

I am asking for the documentation and articles, the "FM" part of the
"RTFM". I'd be grateful for any tips.
