Hello,
I'm trying to test run test coverage using master branch on Debian 13 with:
postgres@alma:~$ lcov --version
lcov: LCOV version 2.0-1
postgres@alma:~$ gcov --version
gcov (Debian 14.2.0-19) 14.2.0
JSON format version: 2

If I build PG with make using:
./configure --prefix=$TARGET --enable-cassert --enable-debug
--with-uuid=e2fs --with-openssl --enable-tap-tests
--enable-injection-points --with-liburing --enable-coverage
I get:

Yeah, recent versions of lcov are rather broken :-(.
Best bet is to apply "--ignore-errors" liberally,
and even then you'll get a bunch of useless warnings.
The output seems correct despite all that.
My coverage-running script currently does this so that
I don't see any complaints:
-----
# In RHEL 10.1 (LCOV version 2.0-1), we need a bunch of options
# to silence useless-and-probably-bogus warnings.
make -s coverage-html \
LCOVFLAGS="-q --ignore-errors gcov,gcov" \
GENHTML_FLAGS="-q --legend --ignore-errors unmapped,unmapped" \
2>&1 | grep -v -e 'gcno:no functions found$' -e '^stderr:$' \
-e 'WARNING: Duplicate specification "base-directory' \
-e 'WARNING: Duplicate specification "build-directory'
-----
You might want to leave out the "grep -v" part until you've
satisfied yourself that no interesting messages are produced
on your installation.
regards, tom lane

Yeah, lcov is apparently broken at the moment and requires some flags to
turn some of its errors into warnings. This thread has some recipes
that may be helpful:
https://postgr.es/m/akgWI8Cixc9b_7uB@alvherre.pgsql
I haven't tried with Meson, but maybe simply setting the same
environment variables is enough.
Some patches were offered, but I haven't tried them (yet):

BTW the reports generated for branch master are at
https://coverage.postgresql.org/ (normal report)
and
https://coverage.postgresql.org/diff/ (differential coverage)

I did not know master branch test coverage reports.
Thanks.
