So I could open, for exemple, 5 db connections (with PQconnectdb()) and
then create 5 threads and use those connections in eache thread. But how
about use PQreset() or PQfinish() inside the new created threads?
I used to test connection before send a query like bellow:
if(PQstatus(con)==CONNECTION_BAD) {
PQreset(con);
if(PQstatus(con)==CONNECTION_BAD) erro_fatal();
}
Should I protect the calls to those functions by an mutex?? Could it
work??? Which functions read or alter Qconnectdb()'s static array??
I think it is important to mark wich functions in Libpq is thread safe or
not.
