Re: Monitoring database for changes - backup purposes

Chris,

If you have a JDBC driver for pgsql, you can use SchemaCrawler.
https://sourceforge.net/project/showfiles.php?group_id=148383

SchemaCrawler is a free, open source tool that can produce database
schema metadata and/ or data output in a diff-able format.

Sualeh.
