delta/postgresql.git/doc/src/sgml/indexcost.sgml, branch master

Write some real documentation about the index access method API.

2005-02-13T03:04:15+00:00

Change -> and <- to use proper ampersand markups.

2005-01-22T22:06:27+00:00

HEAD and 8.0.X.

$Header: -> $PostgreSQL Changes ...

2003-11-29T19:52:15+00:00

Spell checking, consistent terminology.

2003-11-01T01:56:29+00:00

Replace planner's representation of relation sets, per pghackers discussion.

2003-02-08T20:20:55+00:00

Instead of Lists of integers, we now store variable-length bitmap sets.
This should be faster as well as less error-prone.

Extend join-selectivity API (oprjoin interface) so that join type is

2003-01-28T22:13:41+00:00

passed to join selectivity estimators.  Make use of this in eqjoinsel
to derive non-bogus selectivity for IN clauses.  Further tweaking of
cost estimation for IN.
initdb forced because of pg_proc.h changes.

Escape ampersand.

2003-01-14T10:19:02+00:00

Revise cost_qual_eval() to compute both startup (one-time) and per-tuple

2003-01-12T22:35:29+00:00

costs for expression evaluation, not only per-tuple cost as before.
This extension is needed in order to deal realistically with hashed or
materialized sub-selects.

Add a bunch of pseudo-types to replace the behavior formerly associated

2002-08-22T00:01:51+00:00

with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

Spell checking and markup additions
