Обсуждение: mingw: is configure --without-zlib ok?

My mingw system doesn't zlib installed.

Is it safe to make a build with './configure --without-zlib'?

What's the consequences of doing this?  Will something not work properly in
the resulting psql application/database?

There does appear to be a mingw port of zlib, should I install that before
proceeding?

AFAIR the only thing you lose is the ability to create or read
compressed custom-format dump files in pg_dump/pg_restore.  You
can certainly live without this --- unless you need to read
compressed dumps that someone else sends you.

And it is in our manual:

      The <productname>zlib</productname> compression library will be
      used by default. If you don't want to use it then you must
      specify the <option>--without-zlib</option> option for
      <filename>configure</filename>. Using this option disables
      support for compressed archives in <application>pg_dump</> and
      <application>pg_restore</>.
