pgquarrel 0.4 released

A new pgquarrel version was released. When I started to develop pgquarrel I wanted a software that was: (i) PostgreSQL-centric, (ii) supports different PostgreSQL versions, (iii) does not depend on other software, (iv) run faster, (v) multiplatform, and (vi) flexible. There were a lot of migration tools out there but all of them are generic (it couldn't show me that a reloption was changed or that a new domain was created). After another release, the light in the end of the tunnel seems closer than when I started to code.

pgquarrel supports the most important objects:

• tables;
• indexes;
• functions;
• views;
• materialized views;
• schemas;
• sequences;
• triggers;
• types;
• domains.

It also supports PostgreSQL-centric objects such as:

• extensions;
• rules;
• event triggers;
• text search;
• operators;
• security labels.

This new release adds support for partitioning, typed tables, and extended statistics. It adds options to select what kind of objects you want to compare. It also adds a bunch of command line options that turns pgquarrel script-friendly (it is no longer necessary to create a configuration file).
