Re: BUG #15170: PQtransactionStatus returns ACTIVE after Empty Commit

I do not see that here; for instance, the attached test program prints

Initial PQtransactionStatus: 0
PQtransactionStatus after BEGIN: 2
PQtransactionStatus after COMMIT: 0
PQtransactionStatus after BEGIN; COMMIT: 0

which is what I'd expect (0 is PQTRANS_IDLE, 2 is PQTRANS_INTRANS).
I'd only expect PQTRANS_ACTIVE if libpq thinks a query is still "in
flight", ie the server hasn't returned a command-complete message.

I speculate that either you or PHP have not waited for the commit
response to come back ... but without a concrete example to look at,
it's hard to say more.
