Fixed, I thought ... yeah, here:

2007-06-07 17:45 tgl

* src/backend/: access/transam/xact.c, storage/ipc/procarray.c,
utils/error/elog.c: Redefine IsTransactionState() to only return
true for TRANS_INPROGRESS state, which is the only state in which
it's safe to initiate database queries. It turns out that all but
two of the callers thought that's what it meant; and the other two
were using it as a proxy for "will GetTopTransactionId() return a
nonzero XID"? Since it was in fact an unreliable guide to that,
make those two just invoke GetTopTransactionId() always, then deal
with a zero result if they get one.
