It's not very robust to assume that each inserted row will produce exactly one WAL record and that no other WAL records will be generated in the process, because for example a particular transaction could always be the one that has to extend clog. Because these tests are not run by 'make installcheck' but only by 'make check', it may be that in our current testing infrastructure this can't be hit, but it doesn't seem like a good idea to rely on that, since unrelated changes to the regression tests or the way write-ahead logging is done could easily cause it to start happening, and debugging such failures is a pain. Adjust the regression test to be less sensitive. Anton Melnikov, reviewed by Julien Rouhaud Discussion: http://email@example.com
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:
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
