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 tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
