## Description

In PostgreSQL 9.3.x before 9.3.17, 9.4.x before 9.4.12, 9.5.x before 9.5.7,
and 9.6.x before 9.6.3, it was found that the PGREQUIRESSL environment
variable was no longer enforcing a SSL/TLS connection to a PostgreSQL
server. An active Man-in-the-Middle attacker could use this flaw to strip
the SSL/TLS protection from a connection between a client and a server.
