Why are only select, insert, update, and delete supported for $X binds?
This is a property of the way prepared statements are implemented.
Prepared statement parameters can be used in the place of expressions in
optimizeable statements (the

I need to build custom win32 binary package for PostgreSQL.
I've downloaded source for PGinstaller but found them hard to

Things I need to modify:

I've got problems building the client libraries. It seems that there this

Patch applied to CVS HEAD and 8.1.X. Thanks.
Borland CC also needed this change, so I modified your patch appropriately.

Just to follow up on the discussion of that thread: what's been
implemented is a way to store arbitrary name=value strings in an index's
pg_class entry, and to make these available in a pre-parsed form through

I've recently migrated one of my databases to using veil. This involved
creating a 'private' schema and moving all tables to it. Functions
remain in public, and secured views are created there which can be
accessed by normal users.
In doing so, I found to my extreme displeasure that although the

Thanks for the stats Andrew. Out of interest, can you easily tabulate

Or, more generally, even put a dump of the DB (without personal infos

OK, but the point of the question is that constantly updating
a single row steadily degrades performance, would
delete/insery also do the same?
Yes, there is currently no difference (so you should do the update).
Of course performance only degrades if vaccuum is not setup correctly.

Which is faster will probably depends on what is more common in your DB:
row already exists or not. If you know that 99% of the time the row
will exist, the update will probably be faster because you'll only
execute one query 99% of the time.

I'm a bit confused about how scan keys work. Is there any simple way given a
list of Datums of the same type as the index tuple attributes to get all
matching index entries? This is for a non-system index.
It seems like the only place in the code where non-system index lookups are
done is

I could arrange a dump without the diagnostics, in these 2 tables:

compiler_version | architecture

I am well aware of what security definer means. The significant part of
this example is that lastval() will allow the caller to see the value of
a sequence where currval('seq') will not. This means that things which
might have been forbidden in 8.0 are now accessible in 8.1.
