Oracle to PostgreSQL Tool

Hi all,

Here the latest version and first working release of Ora2Pg a tool to export
Oracle database to PostgreSQL.

It currently dump the database schema (tables, views, sequences,
indexes, grants), with primary, unique and foreign keys into PostgreSQL
syntax without editing the SQL code generated. You can dump only a
particular schema from the Oracle database.

Functions, procedures and triggers with SQL or PLSQL code generated must
be reviewed to match the PostgreSQL syntax. Some usefull recommandation
on porting Oracle to PostgreSQL can be found at
http://techdocs.postgresql.org/
under the "Converting from other Databases to PostgreSQL" Oracle part. I
just
notice one thing more is that the trunc() function in Oracle is the same for
number
or date so be carefull when porting to PostgreSQL to use trunc() for number
and
date_trunc() for date.

I will add more precision in type NUMBER conversion based on length to match
as closest as possible all rich PostgreSQL numerics type. But it seems not to be

urgent as it seems that Oracle DBAs only create number with length 22 (default)
Space seems not to be their problem...

The following need help :

- SQL query converter.
- SQL/PLSQL code converter.
- Extracting/converting data for loading into PostgreSQL.

By this I mean replacing Oracle function by PostgreSQL one's into the SQL code
and reformat some type to match PostgreSQL syntax.

Extract data as text seem not be possible with Oracle so the only way is to
select data from oracle and convert them on the fly by a online program.

Latest version (1.3) will be available under /contrib soon (thanks to Bruce)
but you can find it now at http://www.samse.fr/GPL/ora2pg/
