使用meson编译postgresql的方法
meson 是一个相对较新的构建系统，力求快速且易于使用。现在postgresql已经支持meson编译，这篇博文会介绍如何使用meson编译新版postgresql。
请确认postgresql源码目录中存在meson.build，如果没有请升级源码版本。
1 编译过程
工具与编译目录结构
yum install -y ninja-build meson
# 源码目录
pgroot99/pgsrc
# 新建构建目录
pgroot99/pgbuild第一步
进入构建目录pgroot99/pgbuild
cd pgroot99/pgbuild
meson setup . ../pgsrc/如果出现The conflicting files need to be removed提示，请到源码目录执行maintainer-clean，彻底清理源码目录：
export PGHOME=xxx
./configure --prefix=$PGHOME --enable-tap-tests --with-tcl --enable-depend --enable-cassert --enable-debug --with-perl --with-openssl --with-libxml CFLAGS="-ggdb -O0 -g3 -gdwarf-2"
make maintainer-clean第二步：配置intro-buildoptions.json
进入构建目录pgroot99/pgbuild
所有可选参数名称与值都在文件meson-info/intro-buildoptions.json中，如果有新加参数名称不对可以到这个文件中查询。
meson configure \
-Dprefix=${PGHOME} \
-Dtap_tests=enabled \
-Dcassert=true \
-Dbuildtype=debug \
-Ddebug=true \
-Doptimization=0 \
-Dlibxml=enabled \
-Dc_args="-ggdb -O0 -g3 -gdwarf-2" 第三步：编译、安装（默认会使用CPU核数编译）
进入构建目录pgroot99/pgbuild
