Hello,

 

We are having a deadlock issue when executing multiple select statements from multiple threads, the issue happens with driver version (9.6.4.0) or newer, doesn’t happen on 9.6.3.1 .

I’ve attached a simple project that triggers the deadlock, tested with visual studio 2017, release x64 build, PostgreSQL 10.3, usually happens after few runs.[please note that the proper database connection string and the table names need to be provided in the code for it to work].

I’ve also included the stack trace of the two threads in deadlock.

 

Regards,

Ayman
