The original coding here was very confusing, because it named the two servers it set up "master" and "slave" even though it swapped their replication roles multiple times. At any given point in the script it was very unobvious whether "$node_master" actually referred to the server named "master" or the other one. Instead, pick arbitrary names for the two servers --- I used "london" and "paris" --- and distinguish those permanent names from the nonce references $cur_master and $cur_slave. Add logging to help distinguish which is which at any given point. Also, use distinct data and transaction names to make all the prepared transactions easily distinguishable in the postmaster logs. (There was one place where we intentionally tested that the server could cope with re-use of a transaction name, but it seems like one place is sufficient for that purpose.) Also, add checks at the end to make sure that all the transactions that were supposed to be committed did survive. Discussion: https://postgr.es/m/28238.1499010855@sss.pgh.pa.us |

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/.
