Hello,
I hope to be on the right mail adress. Here are the details of a detected error :
- OS : Windows 2012
- pgsql_odbc version : 09.05.0400
- driver : psqlodbc35w.dll
- database version : 9.5.4 & 9.6.1 (and others?)
- attached a sample of MyLog
The driver can't connect to the database, with no visible error. This occurs when at least one of two settings postgresql.conf are defined as follows :
log_min_duration_statement = 0 or log_duration = on
Sorry for my bad english 
Hope this will help you.
Best regards.
