Resolve a number of oddities in the Java build. First, remove the weird
redirections between the build files, which didn't work completely. Now
you just go to the directory of your choice and run make. Clean up the
build files to have a logical order, fix the unnecessary rebuilds, prevent
the deleting targets from removing files they're not responsible for. Ant
1.3 does not have a bug. It deletes directories just fine if you follow
the documentation.

Prohibit a column from appearing twice in a PRIMARY KEY or UNIQUE
constraint. This case (a) is useless, (b) violates SQL92, and
(c) is certain to cause a failure downstream when we try to create
an index with duplicated column names. So give an appropriate error
message instead of letting the index failure occur. Per report from
Colin Strickland. NOTE: currently, CREATE INDEX fooi ON foo(f1,f1)
still fails with 'cannot insert duplicate key' error. Should we
change that too? What about functional indexes?

Under new theory of operation wherein postmaster forks children
immediately, we will fork a child even if the database state does not
permit connections to be accepted (eg, we are in recovery mode).
The child process will correctly reject the connection and exit as
soon as it's finished collecting the connection request message.
However, this means that reaper() must be prepared to see child
process exit signals even while it's waiting for startup or shutdown
process to finish. As was, a connection request arriving during a
database recovery or shutdown would cause postmaster abort.

Fix VACUUM so that it can use pages as move targets even if they do not

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...
