Problem is: to offer such a thing with a straight face, we'd have to
confine ourselves to an Oracle-subset version of SQL. For instance,
lose the ability to distinguish empty-string from NULL.
I wasn't saying we write it - let Oracle do it :D

If there smart enough to
be buying innobase these days, you can bet that by now they have this stuff
all straightened out.
No, that doesn't seem to follow ... if Oracle are spending their
resources to attack MySQL rather than us, the conclusion would be that
they are clearly still more
As Andrew noted, we've already heard plenty of FUD from Oracle. What
we've not seen is a FUD campaign based on serious study of our
weaknesses --- they've only bothered to muster transparent attacks on
open source DBs in general. My prediction is that the next step will
be FUD that's really
1) PostgreSQL to Oracle database conversion utilities released by
Oracle (unlikely given extensible languages in PostgreSQL).
Strangely a pgsql to oracle exporter is a good thing. It'd be a great
feature of PostgreSQL. Imagine how many people would start on
PostgreSQL if they KNEW that one
Please don't make this assumption. PostgreSQL is *very* much on their radar,
and probably represents the biggest long-term threat to their core database
business at the moment. We got a hint of that during the .org bidding, but
for now it is in Oracle's interest not to call attention to
Argh! That's some sed coolness :)

Hi;

So far, the checklist I can see includes:

What I think we need is a C program that dumps directly from MySQL into
PostgreSQL sql.
ie. Take the mysqldump source code and just modify its output.
Will inherit the MySQL license though :(

I think one of the more difficult areas will be to convert unsigned
fields from mysql into postgres. For smaller sizes it is possible to
convert to postgres by moving one size up and using constraints to
restrict numbers to be positive, and possibly within the mysql range
too. But, the

I need a db connection pooling in PHP. As far I know persistent

SQLRelay. Does anyone have any experience using PostgreSQL + PHP +

Try pgpool.

I don't care how but I need to emulate ENUM type, just to convert
MySQL dumps to PostgreSQL. E.g. ENUM values
stored in MySQL dump should be restorable in Postgres without any
conversion.
In MySQL, ENUM is like this:
