The configuration parameter autocommit
has been disabled since version 7.4, released in 2003.
Up to PostgreSQL version 9.4 the parameter was still present, but had no effect.
From PostgreSQL 9.5 on (released in January 2016), the parameter has been removed, and trying to set it will cause an error message.
Try to update your client software to a more recent version.
