[development] update.php and postgres 7.4

I wrote the schema SQL generator for PostgreSQL and I guess I
suspected it would not work with 7.4.  I developed on Windows which
does not support pg 7.4 so I had no way to test with that platform.  I
probably should have made some noise about that.

I don't know enough about the pg-using community to know whether
support for 7.4 matters.

If you have a patch, I suggest submitting it.  The conversation about
what to do re: pg 7.4 can then happen in that thread.

Have you tried schema.module on pg 7.4?  I'm curious to know whether
its database schema inspection code works...

Thanks,

Barry
