https://bugs.ruby-lang.org/issues/16283#change-82375

* Author: doloopwhile@gmail.com (������ ������)
* Status: Third Party's Issue
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin18]
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
Call Kernel#fork in transaction of Postgres and call some Socket method in fork's block, then ruby on the child process abort with segmentation fault.

Conceptual code:

```
MGModel.connection.transaction do

  # Do something

  fork do
    Socket.gethostbyname('localhost') # <- Segmentation fault.
  end
end
```

Expected behavior: The child process successfully exists or raises exception.

Please see attached files for Reproduction code and full error log.
