Tom Lane	0e314d747e	Add safety check on expression nesting depth. Default value is set by a config.h #define, and the runtime value can be controlled via SET.	26 years ago
Tom Lane	18baa9790e	Looks like I broke SET variable = DEFAULT awhile ago. Ooops.	26 years ago
Tom Lane	f46571165d	Get rid of postgres.c's separate parsing logic for PGDATESTYLE env. variable, instead calling same code in variable.c that is used to parse SET DATESTYLE. Fix bug: although backend's startup datestyle had been changed to ISO, 'RESET DATESTYLE' and 'SET DATESTYLE TO DEFAULT' didn't know about it. For consistency I have made the latter two reset to the PGDATESTYLE-defined initial value, which may not be the same as the compiled-in default of ISO.	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
Tom Lane	71ed7eb494	Revise handling of index-type-specific indexscan cost estimation, per pghackers discussion of 5-Jan-2000. The amopselect and amopnpages estimators are gone, and in their place is a per-AM amcostestimate procedure (linked to from pg_am, not pg_amop).	26 years ago

Tom Lane	3d87216ab9	Get rid of some minor compiler warnings. (HP's cc doesn't like if you forward-declare a routine static, and then don't make it static in the actual definition...)	28 years ago

Bruce Momjian	7b2b779a2a	Add auto-size to screen to \d? commands. Use UNION to show all \d? results in one query. Add \d? field search feature. Rename MB to MULTIBYTE.	28 years ago
Bruce Momjian	cb7cbc16fa	Hi, here are the patches to enhance existing MB handling. This time I have implemented a framework of encoding translation between the backend and the frontend. Also I have added a new variable setting command: SET CLIENT_ENCODING TO 'encoding'; Other features include: Latin1 support more 8 bit cleaness See doc/README.mb for more details. Note that the pacthes are against May 30 snapshot. Tatsuo Ishii	28 years ago
Bruce Momjian	6bd323c6b3	Remove un-needed braces around single statements.	28 years ago
Bruce Momjian	9a0dd4fb18	There's a patch attached to fix gcc 2.8.x warnings, except for the yyerror ones from bison. It also includes a few 'enhancements' to the C programming style (which are, of course, personal). The other patch removes the compilation of backend/lib/qsort.c, as qsort() is a standard function in stdlib.h and can be used any where else (and it is). It was only used in backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c, and backend/storage/page/bufpage.c > > Some or all of these changes might not be appropriate for v6.3, since we > > are in beta testing and since they do not affect the current functionality. > > For those cases, how about submitting patches based on the final v6.3 > > release? There's more to come. Please review these patches. I ran the regression tests and they only failed where this was expected (random, geo, etc). Cheers, Jeroen	28 years ago
