When does PQstatus() update?

Hi,

Just wondering when the result of the function PQstatus() gets updated?
Can I expect it to be updated while connected even without performing any
transactions/communications with the backend?

I tried PQexec()'ing a "BEGIN TRANSACTION" on a dead backend and
immediately checked PQstatus() as well as PQresultStatus(). PQstatus()
returned a CONNECTION_OK while PQresultStatus() returned
PGRES_FATAL_ERROR. I tried it again on the same dead-connection backend a
couple of seconds later and got a CONNECTION_BAD fro PQstatus() and a
PGRES_NONFATAL_ERROR from PQresultStatus().
