Michael Paquier a3ab7a707d Fix corner case with 16kB-long decompression in pgcrypto, take 2 ... A compressed stream may end with an empty packet. In this case decompression finishes before reading the empty packet and the remaining stream packet causes a failure in reading the following data. This commit makes sure to consume such extra data, avoiding a failure when decompression the data. This corner case was reproducible easily with a data length of 16kB, and existed since e94dd6a. A cheap regression test is added to cover this case based on a random, incompressible string. The first attempt of this patch has allowed to find an older failure within the compression logic of pgcrypto, fixed by b9b6105. This involved SLES 15 with z390 where a custom flavor of libz gets used. Bonus thanks to Mark Wong for providing access to the specific environment.
