Hello,

The code:
https://github.com/alphaonex86/CatchChallenger/blob/master/server/main-=
epoll.cpp#L552
https://github.com/alphaonex86/CatchChallenger/blob/master/server/epoll=
/db/EpollPostgresql.cpp
But the simple server work, no difference of code:
https://github.com/alphaonex86/CatchChallenger/blob/master/tools/epoll-=
server/epoll-psql/main.cpp

In my implementation, valgrind break the postgresql connexion. With gdb=
 or normal:
Connexion CONNECTION_MADE
datapack_loaded not loaded: but database have not the event EPOLLIN
Connexion CONNECTION_AWAITING_RESPONSE
datapack_loaded not loaded: but database have not the event EPOLLIN
Connexion CONNECTION_AWAITING_RESPONSE
datapack_loaded not loaded: start preload data=20

Under valgrind:
Connexion CONNECTION_MADE
datapack_loaded not loaded: but database have not the event EPOLLIN
Connexion CONNECTION_AWAITING_RESPONSE
datapack_loaded not loaded: but database have not the event EPOLLIN

In both case:
netstat -nap | grep postgres:
unix  2      [ ACC ]     STREAM     LISTENING     832      -           =
         /run/postgresql/.s.PGSQL.5432
unix  3      [ ]         STREAM     CONNECTED     17572580 -           =
         /run/postgresql/.s.PGSQL.5432


Other problem, but very less problematic, in simple and complex case:
PQconnectStart("dbname=3Dcatchchallenger user=3Droot"); -> work
PQconnectStart("host=3Dlocalhost dbname=3Dcatchchallenger user=3Droot")=
; -> don't work
I have:
Connexion CONNECTION_STARTED, Connecting...
Connexion status: PGRES_POLLING_OK
EPOLLPRI
And after lot of time:
Connexion CONNECTION_MADE, Connected to server...
Connexion status: PGRES_POLLING_ACTIVEepoll_ctl, socket ready to write
epoll_ctl, socket ready to read
query repeat send failed
epoll_ctl, socket closed

=2Dh localhost with psql work perfectly.

Thanks in advance for you help.
Cheers,
