Dear All,

As I solution, I wanted to start to build Postgres from source by myself, in 
order to better managed what it is finally included. 
So I wanted to compile on Windows with Visual Studio.

However, in the page 
https://www.postgresql.org/docs/current/install-windows.html, I can see:
   " It is recommended that most users download the binary distribution for 
Windows, available as a graphical installer package from the PostgreSQL 
website. Building from source is only intended for people developing PostgreSQL 
or extensions. "

Why this recommendation ? Is there any "risk" by building from source ?

Best regards,

Not nice.

That depends on how PostgreSQL was configured.

It may be a bit cumbersome, but you could go through all the shared libraries
(DLLs) in the "bin" directory that do not belong to PostgreSQL.  The licenses 
for software like OpenSSL should be easy to find.

Yours,
