Article about migration from Oracle to PostgreSQL with Ora2pg

I wrote a article about migration large set of PL/SQL procedures to Postgres. This article is in Czech language, but Google translator works.

New Ora2pg is available

I am a happy user of Ora2pg - mainly because it really helps with my work. Year ago Ora2pg has minimal support for PL/SQL to PL/pgSQL conversion. Now, this conversion is very well supported. Sure, PL/SQL and Oracle are very large/rich language (environment), so is not possible to support all patterns, but some basic and often used patterns are supported already. What I have to say - a cooperation with Gilles Darold is perfect - see: Ora2Pg v18.2 has been released.
