Ora2Pg v18.4 has been released

Paris, France - April 24th, 2016

**Ora2Pg 18.4 released**

Version 18.4 of Ora2Pg, a free and reliable tool used to migrate an
Oracle database to PostgreSQL, has been officially released and is
publicly available for download.

This is a maintenance release to fix several issues reported by users.
There is also some major data export speed improvement thanks to the
work of PostgreSQL Pro and a new RPM spec file provided by Devrim
Gündüz to be able to build RPM package for Ora2Pg.

Details of data export speed improvement are explained in the following
article:
http://blog.dalibo.com/2016/04/06/Ora2Pg_data_export_improvement.html

There is a new configuration directive:

  * EMPTY_LOB_NULL: when enabled force empty_clob() and empty_blob()
    to be exported as NULL instead as empty string.

Here is the complete list of other changes:

  - Put parenthesis around AT TIME ZONE expression
  - Add EMPTY_LOB_NULL directive to force empty_clob and empty_blob()
    to be exported as NULL instead as empty string. This might improve
    data export speed if you have lot of empty lob. Thanks to Alex
    Ignatov for the report.
  - Fix import_all.sh script to import grant and tablespace separately
    as postgres user and just after indexes and constraints creation.
  - Add parsing of tablespace from "alter table ... add constraint"
    with DDL input file. Thanks to Felipe Lavoura.
  - Remove --single-transaction in import_all.sh with TABLESPACE
    import. Thanks to Guillaume Lelarge for the report.
  - Fix Makefile.PL to used with latest spec file from Devrim Gündüz
    and following the advice of calbiston.
  - Update spec file to v17.4 and latest change to Makefile.PL
  - Replace ora2pg.spec by postgressql.org spec file by Devrim Gunduz.
  - Generate man page to avoids rpmbuild error.
  - Fix Windows install. Thanks to Lorena Figueredo for the report.
  - Remove "deferrability" call for mysql foreign keys. Thanks to
    Jean-Eric Cuendet for the report.
  - Fix issue in restoring foreign key for mysql data export. Thanks
    to Jean-Eric Cuendet for the report.
  - Remove connection test to PostgreSQL instance as postgres or any
  - Fix creation of configuration directory.
  - Fix Makefile to dissociate CONFDIR and DOCDIR from PREFIX or
    DESTDIR. Thanks to Stephane Schildknecht for the report.
  - Fix date_trunc+add_month replacement issue. Thanks to Lorena
    Figueredo for the report.
  - Do not replace configuration directory in scripts/ora2pg if this
    is a RPM build. Thanks to calbiston for the report.
  - Return empty bytea when a LOB is empty and not NULL.
  - Regular expressions and conditions checks improvement in method
    format_data_type() to make it a bit faster on huge tables. Thanks
    to Svetlana Shorina for the patch.
  - Fix INSERT using on the fly data import with boolean values.
    Thanks to jecuendet for the report.
  - Allow MySQL data type to be converted into boolean. Thanks to
    jecuendet for the report.
  - Fix export of BIT mysql data type into bit bit varying. Thanks
    to jecuendet for the report.
