我最近不得不在macOS Mojave上使用homebrew将Postgres版本从10升级到11，由于需要使用Postgis，遵循标准的{{1 }}，然后升级Postgres版本。
我发现this gist似乎可以解决我的问题。当我尝试在brew postgresql-upgrade-database上运行make时，抛出一个错误，似乎使postgis-2.5.1与Command Line Tools路径混淆了，而我目前尚未安装。
下面，我粘贴到目前为止已经尝试过的命令序列：

之前在sysroot上显式设置了./configure路径还是设置了CMAKE_OSX_SYSROOT，它也不起作用。
make作为记录，我已经安装了❯ ./configure --with-sysroot=/Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/ --with-pgconfig=/usr/local/Cellar/postgresql@10/10.6_1/bin/pg_config --with-xml2config=/usr/local/Cellar/libxml2/2.9.9_2/bin/xml2-config --with-projdir=/usr/local/Cellar/proj/5.2.0 --with-jsondir=/usr/local/Cellar/json-c/0.13.1 --with-pcredir=/usr/local/Cellar/pcre/8.4

和here，它们可能是必需的。{p>
我非常感谢我做错事情的任何线索或技巧，或者可以解决问题的其他方法。
谢谢！

经过大量的努力，我最终将旧数据库与以下内容一起转储：
pg_dumpall > /tmp/my_databases.sql
，然后安装新的Postgres，并使用以下命令将所有数据恢复回新版本：
psql -f /tmp/my_databases.sql
我希望它将来对其他人有帮助。
