Waste of time, assuming you are thinking of PQstatus(); it just returns
a field from the PGconn struct showing the last known state.
I'd suggest that *upon error* you check to see if the error indicates
a dead connection, and attempt reconnect if so. No need to expend
cycles in the main line of your app for this.
If you really want an end-to-end connectivity check, you can issue
an empty query string with PQexec; but I'd not recommend doing that
for every single query...
