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: http://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 http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.

Heikki noticed in 544E23C0.8090605@vmware.com that slot.c and snapbuild.c were missing the FIN_CRC32 call when computing/checking checksums of on disk files. That doesn't lower the the error detection capabilities of the checksum, but is inconsistent with other usages. In a followup mail Heikki also noticed that, contrary to a comment, the 'version' and 'length' struct fields of replication slot's on disk data where not covered by the checksum. That's not likely to lead to actually missed corruption as those fields are cross checked with the expected version and the actual file length. But it's wrong nonetheless. As fixing these issues makes existing on disk files unreadable, bump the expected versions of on disk files for both slots and logical decoding historic catalog snapshots. This means that loading old files will fail with ERROR: "replication slot file ... has unsupported version 1" and ERROR: "snapbuild state file ... has unsupported version 1 instead of 2" respectively. Given the low likelihood of anybody already using these new features in a production setup that seems acceptable. Fixing these issues made me notice that there's no regression test covering the loading of historic snapshot from disk - so add one. Backpatch to 9.4 where these features were introduced.
