Set random_page_cost to 1.0 to produce more reasonable plans. This is similar to what timescaledb-tune would set. This patch also adds test/pgtest.conf which is only used as postgresql.conf for running the PostgreSQL test suite, because the random_page_cost change lead to test failures in the PostgreSQL test suite.
PostgreSQL tests for TimescaleDB
The CMake configuration within this directory makes it possible to run the standard PostgreSQL test suite with the TimescaleDB extension loaded. This is useful to ensure that TimescaleDBs modifications planner and DDL hooks are compatible with standard PostgreSQL.
Running
The configuration within adds a new CMake target, pginstallcheck,
that allows running the PostgreSQL test suite using a modified test
schedule. The target requires access to the PostgreSQL source code,
which can be configured via the PG_SOURCE_DIR CMake variable. The
source tree needs to be compiled, at least the src/test/regress
directory. If the path to a PostgreSQL source tree is not
auto-detected, this variable can be set manually to point to the right
location.
# In top-level directory of a TimescaleDB source tree
$ mkdir build && cd build
$ cmake -DPG_SOURCE_DIR=<path/to/pg/source> ..
Once CMake is correctly configured, run:
$ make pginstallcheck
