If tools like `pg_regress` or `pg_isolation_regress` are not found, an
error is generated telling you that you need to disable the tests
explicitly using `REGRESS_CHECKS`. This is an inconvenience for the
user since in most cases you just want to build the system with what
you have.
This commit changes that by automatically disabling regression tests,
isolation tests, TAP tests, and formatting targets when tools cannot be
found, which means that users do not normally have to disable tests
explicitly. A notice is still printed that the targets are not added.
In addition, the commit adds an option `REQUIRE_ALL_TESTS` for the rare
case when you want to make sure that all tests are indeed executed (for
example, in CI runs), which by default is off.
Install the Perl prerequisites when building the image for ABI tests,
including the `prove` binary.
Although the ABI tests currently don't run TAP tests, CMake still
failed the configuration since it expects the prerequisites to be
installed unless it is run with `-DTAP_CHECKS=off`.
Adding checks for `pg_isolation_regress` and `pg_regress` and not
running the tests if the programs cannot be found either installed in
default directories or provided with the `PG_PATH` variable, or the
`PG_SOURCE_DIR` variable.
Previously the compile image for the ABI tests was based on a different
postgres image than the run image (e.g. 10-alpine vs 10.2-alpine). This
created dependency problems between different version of ssl packages
that may be available under different alpine versions.
We fix this by forcing the run image to be based off of the same image
as the compile version.
Test the ABI compatibility of postgres across minor version updates
wrt timescale. Namely, compile the extension on an early minor version
of postgres and test it on the latest snapshot of the major branch.
