Avoid having walreceiver code know explicitly about the precision and underlying datatype of TimestampTz. (There is still one calculation that knows that, which should be replaced with use of TimestampDifferenceMilliseconds; but we need to figure out what to do about overflow cases first.) In support of this, provide a TimestampTzPlusSeconds macro, as well as TIMESTAMP_INFINITY and TIMESTAMP_MINUS_INFINITY macros. (We could have used the existing DT_NOEND and DT_NOBEGIN symbols, but I judged those too opaque and confusing.) Move GetCurrentTimestamp calls so that it's more obvious that we are not using stale values of "now" anyplace. This doesn't result in net more calls, and might indeed make for net fewer. Avoid having a dummy value in the WalRcvWakeupReason enum, so that we can hope for the compiler to catch overlooked switch cases.

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/.
