Sorry that was a mistake from me. Now it appears fine.

Accidentally when testing further on this line I found a crash when invalid

Using host libthread_db library "/lib64/libthread_db.so.1".

0x00007ffff7bb8d4f in PQpass (conn=0x68aaa0) at fe-connect.c:5582

5582 password = conn->connhost[conn->whichhost].password;
