Hi everybody,
maybe you have followed the tread before about migratiing from Oracle
to Postgres. In there I quoted a Document from Oracle called
"Oracle Concepts". In there, Oracle explains exactly, what goes on
under the hood of Oracle.
(Like How they handle concurrency, locking...)
Is there such a document for Postgres already?
Cheers,
Dani
