The issue you're describing sounds a lot like the one that was fixed 
here: 
https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=e6c33d594a004a2c831cdff1a16276347d30f703.

9.3.5 is a really old version. The latest 9.3 minor release is 9.3.22. 
If what you're seeing is the same bug, it has been fixed in the latest 
minor version. Even if it turns out to be something different, you 
really need to upgrade.

Note: 9.3 major version is reaching end of life in September, so you 
should start planning an upgrade to a more recent major version, too.
