The existing documentation defines it as "a command is in progress",
which seems perfectly clear to me --- adding more words would just
muddy the waters.
Also, if a command is running then the server *does* have a transaction
open -- it might be an auto-started, auto-committed one, but there's
always a transaction. You seem to be using that word in a way that does
not correspond with common Postgres usage. (Note that the definitions for
PQTRANS_INTRANS and PQTRANS_INERROR say "transaction block" not
"transaction", to comport with our usual terminology.)
