Dear Tsunakawa-san, Iwata-san,
> * Is setlinebuf() available on Windows? Maybe you should use setvbuf() instead.
Yeah, cfbot2021 throws errors:
https://ci.appveyor.com/project/postgresql-cfbot/postgresql/build/1.0.124922
```
src/interfaces/libpq/fe-connect.c(6776): warning C4013: 'setlinebuf' undefined; assuming extern returning int
[C:\projects\postgresql\libpq.vcxproj]
```
The manpage of setlinebuf() suggests how to replace it, so you should follow.
```
The setbuffer() function is the same, except that the size of the buffer is up to the caller, rather than
being determined by the
default BUFSIZ. The setlinebuf() function is exactly equivalent to the call:
setvbuf(stream, NULL, _IOLBF, 0);
```
