Thanks!  Use yum to install gcc, make, bison, yacc, git,
readline-devel, zlib-devel.  (Hope I'm not forgetting anything
here...)

Pull down the sources:

$ git clone https://github.com/postgres/postgres.git

Go into the source directory:

$ cd postgres

Let's say we want to test with the 11 branch (so you can test against
an existing 11.x development environment database you might have
installed the usual way with packages, as opposed to the master branch
where we are developing 12).  Switch to that branch:

$ git checkout REL_11_STABLE

Create a new branch for this experiment:

$ git checkout -b tolerate-einval

Apply the patch (adjust path to wherever you put the patch):

$ git am 0001-Tolerate-EINVAL-when-calling-fsync-on-a-directory.patch

Configure, build, install (the prefix is where it will install the
resulting binaries, adjust to taste, -j is how many CPUs you have if
you want to build fast):

$ mkdir $HOME/install
$ ./configure --prefix=$HOME/install

$ make -s -j4 && make -s install

Optionally, run a self-test to see if everything is sane:

$ make -s check

Now you should have binaries like $HOME/install/bin/pg_basebackup and
you can test if they work on CIFS.
