Hi, I've successfully set up a slave system using WAL archiving and pg_standby, but I have a couple of questions.
 
I have a couple of questions:
 
Is it possible to stop the database server (for maintenance for example) and resume the recovery without starting afresh and making a complete backup of the original again?

Yes, it won't begin reading at the very first logfile, it will start based on your last checkpoint:


 
Secondly is it possible to start the database in "readonly" (using set default_transaction_read_only) and make a query before resuming the recovery?

No, this feature is only available in 9.0 (which is in alpha) and beyond.
