Bruce Momjian	020be62dea	Well, here's the first pass on regression ... tests for the Foreign Key support in 7.0 which was made against a CVS copy from this afternoon.

Tom Lane	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 ...	26 years ago
Tom Lane	9c80cceb02	Update EXPLAIN documentation to reflect the fact that the ... planner now produces two cost numbers instead of one.	26 years ago
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.	26 years ago

Bruce Momjian	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 :-) Karel ---------------------------------------------------------------------- Karel Zak <zakkr@zf.jcu.cz> http://home.zf.jcu.cz/~zakkr/	26 years ago

Bruce Momjian	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. Keith Parks.	26 years ago

Tom Lane	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...	26 years ago
Bruce Momjian	b866d2e2d7	as attache of this mail is patch (to the main tree) with to_char's ... family functions. Contain: conversion from a datetype to formatted text: to_char( datetime, text) to_char( timestamp, text) to_char( int4, text) to_char( int8, text) to_char( float4, text) to_char( float8, text) to_char( numeric, text) vice versa: to_date ( text, text) to_datetime ( text, text) to_timestamp ( text, text) to_number ( text, text) (convert to numeric) PostgreSQL to_char is very compatible with Oracle's to_char(), but not total exactly (now). Small differentions are in number formating. It will fix in next to_char() version. ! If will this patch aplly to the main tree, must be delete the current to_char version in contrib (directory "dateformat" and note in contrib's README), this patch not erase it (sorry Bruce). The patch patching files: doc/src/sgml/func.sgml ^^^^^^^^ Hmm, I'm not sure if my English... :( Check it anyone (volunteer)? Thomas, it is right? SGML is not my primary lang and compile the current PG docs tree is very happy job (hard variables setting in docs/sgml/Makefile --> HSTYLE= /home/users/t/thomas/.... :-) What add any definition to global configure.in and set Makefiles in docs tree via ./configure? src/backend/utils/adt/Makefile src/backend/utils/adt/formatting.c src/include/catalog/pg_proc.h src/include/utils/formatting.h Karel Zak <zakkr@zf.jcu.cz> http://home.zf.jcu.cz/~zakkr/	26 years ago

Peter Eisentraut	bdb41ad0e7	Made abstime/reltime use int4 instead of time_t (TODO item) ... Made type equivalency apply to aggregates (TODO item) Fixed parsing bug in psql Reverted some stupid options changes I made to pg_dump	26 years ago
Tom Lane	0dbffa704a	First cut at making useful selectivity estimates for range queries ... (ie, WHERE x > lowbound AND x < highbound). It's not very bright yet but it does something useful. Also, rename intltsel/intgtsel to scalarltsel/scalargtsel to reflect usage better. Extend convert_to_scalar to do something a little bit useful with string data types. Still need to make it do something with date/time datatypes, but I'll wait for Thomas's datetime unification dust to settle first. Eventually the routine ought not have any type-specific knowledge at all; it ought to be calling a type-dependent routine found via a pg_type column; but that's a task for another day.	26 years ago
