This v6 series is squashed and rebased on the current master. It also
includes the revisions and clarifications suggested in the previous round
of review, including Michael=E2=80=99s comments.

First of all,thanks for testing the patch.
Sorry for the inconvenience ,here I have attached separate patches for
libpq-exit-check and whitelisting of pthread_exit().

In Michael=E2=80=99s v5 1/2 patch, the configure file had changes because i=
t was
generated after running autoreconf.Is it correct to include generated files
in the patches (such as configure,configure.status or other auto-generated
files).
Or only the change in configure.ac should be part of the patch.

Saying that, passing the path of nm as argument to the perl script is

I agree with the approach of keeping the coverage
condition local to each build system rather than relying on
enable_coverage  as
an environment variable. In practice, autoconf (enable_coverage) and Meson
(b_coverage) expose their coverage settings independently, so duplicating
the
check avoids any accidental cross-build inconsistencies. It also prevents
the
script from having to detect build-system-specific flags internally, keepin=
g
libpq-check.pl focused only on symbol inspection. So I think it makes sense
for Makefile and Meson to each guard their own invocation. What do you
think?

I welcome any additional suggestions regarding the comments or the code.

Regards,
Vasuki M
