Hi All,
Has anyone committed something that would cause me to be getting doubles of
all my ELOG messages? Or is it something I've changed in my local CVS?

The first thing to point out is that the estimated cost is measured in
terms of page reads while the actual time is measured in milliseconds. So
even if the cost estimate is accurate it is unlikely that those numbers
will be the same.

I'd like to implement error codes. I think they would be pretty useful,

We also have implemented a roll forward recovery mechanism. We modified a
7.2.1 version of Postgres.
The mechanism is designed to provide a means of recoverying from the loss or
corruption of media. It provides for duplicating wal_files so that if a
wal_file is lost roll forward recovery can rec
Neil, attached are three email messages dealing with error message
wording.
I like Tom's idea of coding only the messages that are common/user
errors and leaving the others with a catch-all code.
We now have more elog levels in 7.3, so it should be easier to classify
the messages.

One of my machines has two CPUs, and in some cases I build a pair
of indexes in parallel to take advantage of this. (I can't seem
to do an ALTER TABLE ADD PRIMARY KEY in parallel with an index
build, though.) Recently, though, I received the message "ERROR:

I have committed many support files for CREATE CONVERSION. Default
conversion procs and conversions are added in initdb. Currently
supported conversions are:

I don't know how our marketing came up third most popular but I think the
order is, Oracle, MySQL, and PostgreSQL or maybe Oracle, MSSQL and
PostgreSQL. I'm sure there is some criterion by which PostgreSQL is tenth
and by some other its number one.

Yes, our GiST supports variable-length keys.

Does anyone know how I should modify MergeAttributes to support dropped
columns?
If the parent column is dropped, should I perhaps just instead of going:
def = makeNode(ColumnDef);
I could go something like:
def = makeNullNode(); (or whatever the correct function is)
Or should I modify or re
