1、下载源代码：

git clone -b REL_10_STABLE git://git.postgresql.org/git/postgresql.git pg10
cd pg10
git branch
[root@localhost postgresql]# git branch
* REL_10_STABLE

2、安装对应依赖包：

yum install docbook-dtds docbook-style-xsl fop libxslt opensp

参考：https://www.postgresql.org/docs/current/static/docguide-toolsets.html

3、准备工作：

./configure
cd pg10
cd doc/src/sgml

4、编译：

[root@localhost sgml]# make postgres.epub
{ \
  echo "<!ENTITY version \"10.0\">"; \
  echo "<!ENTITY majorversion \"10\">"; \
} > version.sgml
'/usr/bin/perl' ./mk_feature_tables.pl YES ../../../src/backend/catalog/sql_feature_packages.txt ../../../src/backend/catalog/sql_features.txt > features-supported.sgml
'/usr/bin/perl' ./mk_feature_tables.pl NO ../../../src/backend/catalog/sql_feature_packages.txt ../../../src/backend/catalog/sql_features.txt > features-unsupported.sgml

rm postgres.xml.tmp
/usr/bin/xmllint --noout --valid postgres.xml
/usr/share/sgml/docbook/xsl-stylesheets-1.78.1/epub/bin/dbtoepub postgres.xml

[root@localhost sgml]# 
[root@localhost sgml]# ls postgres.epub 
postgres.epub

5、拷贝出来，并进行转换，我是利用软件calibre转换的。
