Copy data from Postgresql to MySQL

Question

I have encountered a problem where I need to copy only data from a Postgresql database to Mysql database. I already have the Mysql database with empty tables. By using PGAdmin I got a backup (data only, without database schema). I tried using PSQL tool but it keeps giving segmentation fault which I couldn't fix at the moment. I am using Ubuntu. Any simple help with a guide will be highly appreciated to copy data.

Answer 1

Use postgres COPY, and MySQL LOAD DATA INFILE.

psql will crash because of out-of-memory if you try to display a few millions of rows because it fetches all the data beforehand to determine the column widths for a prettier display. If you intend to use psql to fetch lots of data, disable this.

Answer 3

It looks like you might be trying to load data into mysql with the postgres client tool. Use the mysql client tools to manipulate data in the mysql server.

mysql client programs

Answer 4
