Hello,
I just have few questions on the replication slots :

- is it possible to get size of the slot?
- if the slave is down, the table grows, when the slave comes up again,
will the table be flushed after pushing wals?
- will they impact performances on the master?

I'm just worried about the size.

Thank you
