sqlsmith 1.0-1 (s390x binary) in ubuntu yakkety

 SQLsmith is a random SQL query generator. Its paragon is Csmith, which proved
 valuable for quality assurance in C compilers.
 .
 It currently supports generating queries for PostgreSQL 9.5 or later only.
 SQLsmith was designed with testing different versions and even products in
 mind, but this has not manifested yet.
 .
 Besides PostgreSQL developers, users developing extensions of PostgreSQL might
 also be interested in exposing their code to SQLsmith's random workload.
 .
 During its prototyping stage, it already found about thirty bugs in
 PostgreSQL alphas, betas and releases, including security vulnerabilities in
 released versions.
