82849df6c6 Add new selectivity estimation functions for pattern-matching operators 
(LIKE and regexp matches).  These are not yet referenced in pg_operator,
so by default the system will continue to use eqsel/neqsel.
Also, tweak convert_to_scalar() logic so that common prefixes of strings
are stripped off, allowing better accuracy when all strings in a table
share a common prefix.

0edcee3459 Fold PQsetenv working state into PGconn, rather than trying to maintain 
it in a separate object.  There's no value in keeping the state separate,
and it creates dangling-pointer problems.  Also, remove PQsetenv routines
from public API, until and unless they are redesigned to have a safer
interface.  Since they were never part of the documented API before 7.0,
it's unlikely that anyone is calling them.

f945f46193 Modify lexing of multi-char operators per pghackers discussion around 
16-Mar-00: trailing + or - is not part of the operator unless the operator
also contains characters not present in SQL92-defined operators.  This
solves the 'X=-Y' problem without unduly constraining users' choice of
operator names --- in particular, no existing Postgres operator names
become invalid.

Also, remove processing of // comments, as agreed in the same thread.

1763a7c1ea Tweak GROUP BY so that it will still accept result-column names, but only 
after trying to resolve the item as an input-column name.  This allows us
to be compliant with the SQL92 spec for queries that fall within the spec,
while still accepting the same out-of-spec queries as 6.5 did.  You'll only
lose if there is an output column name that is the same as an input
column name, but doesn't refer to the same value.  7.0 will interpret
such a GROUP BY spec differently than 6.5 did.  No way around that, because
6.5 was clearly not spec compliant.

598ea2c359 Finish repairing 6.5's problems with r-tree indexes: create appropriate 
selectivity functions and make the r-tree operators use them.  The
estimation functions themselves are just stubs, unfortunately, but
perhaps someday someone will make them compute realistic estimates.
Change pg_am so that the optimizer can reliably tell the difference
between ordered and unordered indexes --- before it would think that
an r-tree index can be scanned in '<<' order, which is not right AFAIK.
Repair broken negator links for network_sup and related ops.
Initdb forced.  This might be my last initdb force for 7.0 ... hope so
anyway ...

9c80cceb02 Update EXPLAIN documentation to reflect the fact that the 
planner now produces two cost numbers instead of one.
 2000-02-15 23:37:49 +00:00
Tom Lane
b1577a7c78 New cost model for planning, incorporating a penalty for random page 
accesses versus sequential accesses, a (very crude) estimate of the
effects of caching on random page accesses, and cost to evaluate WHERE-
clause expressions.  Export critical parameters for this model as SET
variables.  Also, create SET variables for the planner's enable flags
(enable_seqscan, enable_indexscan, etc) so that these can be controlled
more conveniently than via PGOPTIONS.

Planner now estimates both startup cost (cost before retrieving
first tuple) and total cost of each path, so it can optimize queries
with LIMIT on a reasonable basis by interpolating between these costs.
Same facility is a win for EXISTS(...) subqueries and some other cases.

Redesign pathkey representation to achieve a major speedup in planning
(I saw as much as 5X on a 10-way join); also minor changes in planner
to reduce memory consumption by recycling discarded Path nodes and
not constructing unnecessary lists.

Minor cleanups to display more-plausible costs in some cases in
EXPLAIN output.

Initdb forced by change in interface to index cost estimation
functions.

394af52795 I'm sending patch with new version of to_char numbers formatting. 
The PostgreSQL's to_char() is very compatible with Oracle's to_char
 now. I hope that to_char's 3000 rows of source is without bugs, but
 will good if anyone test it, for me it works very well :-)

a64d3bc433 Solaris has always had problems with 1947 in the 
regression tests so I prepared a set of expected
files to make things look OK.

There's also a file to account for minor variations
in the geopmetry output and a resultmap patch to
pull them all together.

With these changes PostgreSQL, from CVS, builds and
regression tests (runcheck) cleanly.

dd979f66be Redesign DISTINCT ON as discussed in pgsql-sql 1/25/00: syntax is now 
SELECT DISTINCT ON (expr [, expr ...]) targetlist ...
and there is a check to make sure that the user didn't specify an ORDER BY
that's incompatible with the DISTINCT operation.
Reimplement nodeUnique and nodeGroup to use the proper datatype-specific
equality function for each column being compared --- they used to do
bitwise comparisons or convert the data to text strings and strcmp().
(To add insult to injury, they'd look up the conversion functions once
for each tuple...)  Parse/plan representation of DISTINCT is now a list
of SortClause nodes.
initdb forced by querytree change...
