标签：postgresql

环境: Ubuntu 14.04, postgresql 9.3, mysql 5.5, wordpress 4.7.1

之前用wordpress 3.4.2和postgresql, pg4wp搭建一个个人博客网站，后来想升级时发现pg4wp从1.3.1之后再也没升级过，这个比较坑了，后续的wordpress都没法再升级上去。没办法，硬着头皮把postgresql替换成mysql。

#postgresql operations，从postgresql上导出数据
\copy wp_postmeta to ‘/home/jerry/postmeta.txt’;
\copy wp_posts ‘/home/jerry/posts.txt’;
\copy wp_links ‘/home/jerry/links.txt’;
\copy wp_terms ‘/home/jerry/terms.txt’;
\copy wp_term_relationships ‘/home/jerry/terms_relationships.txt’;
\copy wp_term_taxonomy ‘/home/jerry/terms_taxonomy.txt’;

 

#mysql operations，新建数据库wordpress， 并导入之前的数据
CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

delete from wp_postmeta;
delete from wp_posts;
delete from wp_links;
delete from wp_terms;
delete from wp_term_relationships;
delete from wp_term_taxonomy;

load data infile ‘/home/jerry/postmeta.txt’ into table wp_postmeta;
load data infile ‘/home/jerry/posts.txt’ into table wp_posts;
load data infile ‘/home/jerry/links.txt’ into table wp_links;
load data infile ‘/home/jerry/terms.txt’ into table wp_terms;
load data infile ‘/home/jerry/terms_relationships.txt’ into table wp_term_relationships;
load data infile ‘/home/jerry/terms_taxonomy.txt’ into table wp_term_taxonomy;
