In my Solana program, users can create program-owned accounts.
Although maybe they want to close it because it is no longer necessary and want to recoup the account rent/fees.
I assume that closing program accounts can only occur from within the program itself, which requires making a dedicated program instruction. Is this common?
If I close the entire Solana program, will all the program-owned accounts also be closed at the same time? If so who will receive all the account fees, and the upgrade auth?
