The existing pg_upgrade/test.sh and the buildfarm code have been holding the same set of SQL queries when doing cross-version upgrade tests to adapt the objects created by the regression tests before the upgrade (mostly, incompatible or non-existing objects need to be dropped from the origin, perhaps re-created). This moves all those SQL queries into a new, separate, file with a set of \if clauses to handle the version checks depending on the old version of the cluster to-be-upgraded. The long-term plan is to make the buildfarm code re-use this new SQL file, so as committers are able to fix any compatibility issues in the tests of pg_upgrade with a refresh of the core code, without having to poke at the buildfarm client. Note that this is only able to handle the main regression test suite, and that nothing is done yet for contrib modules yet (these have more issues like their database names). A backpatch down to 10 is done, adapting the version checks as this script needs to be only backward-compatible, so as it becomes possible to clean up a maximum amount of code within the buildfarm client.

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.
