Thank you for trying to test my patch. As you say, recently commit changes
pg_stat_statements.c a lot. So I have to revise my patch. Please wait for a while.
By the way, latest pg_stat_statement might affect performance in Windows system.
Because it uses fflush() system call every creating new entry in
pg_stat_statements, and it calls many fread() to warm file cache. It works well
in Linux system, but I'm not sure in Windows system. If you have time, could you
test it on your Windows system? If it affects perfomance a lot, we can still
change it.
