We don't actually support session tickets, since we do not create an SSL session identifier. But it seems that OpenSSL will issue a session ticket on-demand anyway, which will then fail when used. This results in reconnection failures when using ticket-aware client-side SSL libraries (such as the Npgsql .NET driver), as reported by Shay Rojansky. To fix, just tell OpenSSL not to issue tickets. At some point in the far future, we might consider enabling tickets instead. But the security implications of that aren't entirely clear; and besides it would have little benefit except for very short-lived database connections, which is Something We're Bad At anyhow. It would take a lot of other work to get to a point where that would really be an exciting thing to do. While at it, also tell OpenSSL not to use a session cache. This doesn't really do anything, since a backend would never populate the cache anyway, but it might gain some micro-efficiencies and/or reduce security exposures. Patch by me, per discussion with Heikki Linnakangas and Shay Rojansky. Back-patch to all supported versions.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
