More or less, yes. (Assuming you're reusing the statement, not just
using it once and discarding it).

It is associated only with the connection that prepared the statement.
The preparation of the statement on the server side is state that's
specific to the connection, and it's not shared between server backend
processes - so the JDBC driver couldn't share statements between
connections even if it wanted to.

No.
