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 ...

new datetime regress test. Someone needs to deal with fixing expected/horology-solaris-1947.out too, assuming we still need it.

Version: 6.5.3-11 Severity: important 'char' is not a signed type by default on powerpc; therefore a character can never be equal to EOF (-1). A patch is attached. Dan /--------------------------------\ /--------------------------------\ | Daniel Jacobowitz |__| SCS Class of 2002 |

Implement "date/time grand unification". Transform datetime and timespan into timestamp and interval. Deprecate datetime and timespan, though translate to new types in gram.y. Transform all datetime and timespan catalog entries into new types. Make "INTERVAL" reserved word allowed as a column identifier in gram.y. Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility routines for all date/time types. date.{h,c} now deals with date, time types. timestamp.{h,c} now deals with timestamp, interval types. nabstime.{h,c} now deals with abstime, reltime, tinterval types. Make NUMERIC a known native type for purposes of type coersion. Not tested.

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.

Add "SESSION_USER" as SQL92 keyword; equivalent to CURRENT_USER for now. Implement column aliases (aka correlation names) and more join syntax. Fix up indenting and tabbing.

Still needs to be done for the general case: "tz+/-#" where tz is a 3 char string. This will probably involve moving code around to other places.

where else to mail it. I am the maintainer of unixODBC, and we have a set of code in our project that started life as the Postgres windows ODBC driver, which has been ported back to unix. Anyway I have just fixed a memory leak in the driver, and I cant see any mention of the fix being done in the main Postgres code, so I thougth I would let you know. Its in the statement.c module, after the COMMIT statement has been executed in SC_Execute, the code was Nick Gorham

this is an old patch which I have already submitted and never seen in the sources. It corrects the datatype oids used in some iterator functions. This bug has been reported to me by many other people. contrib-datetime.patch some code contributed by Reiner Dassing <dassing@wettzell.ifag.de> contrib-makefiles.patch fixes all my contrib makefiles which don't work with some compilers, as reported to me by another user. contrib-miscutil.patch an old patch for one of my old contribs. contrib-string.patch a small change to the c-like text output functions. Now the '{' is escaped only at the beginning of the string to distinguish it from arrays, and the '}' is no more escaped. elog-lineno.patch adds the current lineno of CopyFrom to elog messages. This is very useful when you load a 1 million tuples table from an external file and there is a bad value somehere. Currently you get an error message but you can't know where is the bad data. The patch uses a variable which was declared static in copy.c. The variable is now exported and initialized to 0. It is always cleared at the end of the copy or at the first elog message or when the copy is canceled. I know this is very ugly but I can't find any better way of knowing where the copy fails and I have this problem quite often. plperl-makefile.patch fixes a typo in a makefile, but the error must be elsewhere because it is a file generated automatically. Please have a look. tprintf-timestamp.patch restores the original 2-digit year format, assuming that the two century digits don't carry much information and that '000202' is easier to read than 20000202. Being only a log file it shouldn't break anything. Please apply the patches before the next scheduled code freeze. I also noticed that some of the contribs don't compile correcly. Should we ask people to fix their code or rename their makefiles so that they are ignored by the top makefile? -- Massimo Dal Zotto

a switch statement that has an empty default label. A label of a switch statement must be followed by a statement (or a label which is followed by a statement (or a label which ...)). 3. Files include stringinfo.h failed to compile. The macro, 'appendStringInfoCharMacro' is implemented with a '?:' operation that returns a void expression for the true part and a char expresion for the false part. Both the true and false parts of the '?:' oper- ator must return the same type. Billy G. Allie
