I recently had a client contact me thinking that a CREATE MATERIALIZED
VIEW had somehow managed to keep running in the background after being
^C'd in psql. Turns out this confusion was because their monitoring
eventually complained about the still open (but now aborted)
transaction. The user didn't realize that ^C of a command in an open
transaction would still leave the transaction open.
I'm wondering if there's some way to improve this. One idea is if
TBLOCK_INPROGRESS could also do some of what CleanupTransaction() does
but still leave the status in TBLOCK_ABORT. In particular, release
snapshots. Since there's no substransaction, there's no possibility of
running further commands. Is there risk to that with portals still open?
