Please look at the recovery test failures produced since ed1aad15e, with
pg_stat_statements loaded: [1]. I've reproduced them locally with:
./configure --enable-cassert --enable-debug --enable-tap-tests -q && make -s -j8
echo "
debug_parallel_query = regress
shared_preload_libraries = 'pg_stat_statements'
" >/tmp/test.config
TEMP_CONFIG=/tmp/test.config make -s check -C src/test/recovery/

Best regards,
Alexander
