TAP tests can write
$node->init(no_data_checksums => 1);
to initialize a cluster explicitly without checksums. Currently, this
is the default, but this change allows running all tests with
checksums enabled, like
PG_TEST_INITDB_EXTRA_OPTS=--data-checksums meson test ...
And this also prepares the tests for when we switch the default to
checksums enabled.
The pg_checksums tests need to disable checksums so it can test its
own functionality of enabling checksums. The amcheck/pg_amcheck tests
need to disable checksums because they manually introduce corruption
that they want to detect, but with checksums enabled, the checksum
verification will fail before they even get to their work.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
