Обсуждение: warning on the current head

I am seeing following warning,

In file included from specscanner.c:11:
In file included from ../../../src/include/postgres_fe.h:28:
../../../src/include/c.h:113:9: warning: 'pg_restrict' macro redefined

    Disallow generated columns in COPY WHERE clause

Is someone else also seeing this or I am doing something wrong.

Hmm, maybe you need to run configure again, perhaps after `make
distclean`?  In pg_config.h.in, the "#undef pg_restrict" line was by
commit f0f2c0c1aef9 (Oct. 29), so the Nov. 6 commit should not have
caused problems, unless your pg_config.h is out of date.

Another one, which is more drastic for builds inside the tree, is the
following:
git clean -dxf

I have been relying on this recipe for years to start builds from an
entirely "fresh" state.
