Re: Schema diff tool?

Dave,

The free and open-source SchemaCrawler for PostGresql tool will do
what you need. SchemaCrawler outputs details of your schema (tables,
views, procedures, and more) in a diff-able plain-text format (text,
CSV, or XHTML). SchemaCrawler can also output data (including CLOBs
and BLOBs) in the same plain-text formats. You can use a standard diff
program to diff the current output with a reference version of the
output. SchemaCrawler can be run either from the command line, or as
an ant task. A lot of examples are available with the download to help
you get started.

SchemaCrawler comes with SchemaCrawler Grep, a command line tool that
allows you to search your schema for columns and tables that match a
regular expression. SchemaCrawler can also generate E-R diagrams.

SchemaCrawler is a free, open-source, cross-platform (operating system
and database) tool, written in Java, that is available at
SourceForge:
