Hmm, that may be OK. At first, I felt it strange to treat the server type (primary or standby) as a session attribute.
But we can see the server type as one attribute in a sense that a session is established for. I'm inclined to agree
with:
target_session_attr = {any | read-write | read-only | prefer-read | primary | standby | prefer-standby}
