Jan Wieck	e3cec20ccd	Removed LZTEXT datatype as discussed. ... Jan	26 years ago
Bruce Momjian	7585deb087	I have done the QNX4 port with the current source tree. The number of ... backend/Makefiles to be patched could significantly be reduced since they have been adopted to the QNX4 needs. Andreas Kardos	26 years ago
Jan Wieck	4069d48aa7	Added another single byte oriented decompressor, useful for ... comparision functions. Added all lztext comparision functions, operators and a default operator class for nbtree on lztext. Jan	26 years ago
Jan Wieck	79c3b71c1b	The new LZ compression and an lztext data type based on it. ... Jan	26 years ago
Hiroshi Inoue	05d13cad28	The 1st step to implement new type of scan,TidScan. ... Now WHERE restriction on ctid is allowed though it is sequentially scanned.	27 years ago
Tom Lane	eabc714a91	Reimplement parsing and storage of default expressions and constraint ... expressions in CREATE TABLE. There is no longer an emasculated expression syntax for these things; it's full a_expr for constraints, and b_expr for defaults (unfortunately the fact that NOT NULL is a part of the column constraint syntax causes a shift/reduce conflict if you try a_expr. Oh well --- at least parenthesized boolean expressions work now). Also, stored expression for a column default is not pre-coerced to the column type; we rely on transformInsertStatement to do that when the default is actually used. This means "f1 datetime default 'now'" behaves the way people usually expect it to. BTW, all the support code is now there to implement ALTER TABLE ADD CONSTRAINT and ALTER TABLE ADD COLUMN with a default value. I didn't actually teach ALTER TABLE to call it, but it wouldn't be much work.	27 years ago
Jan Wieck	ccecf1fa46	Added utils/adt/ri_triggers with empty shells for the ... FOREIGN KEY triggers. Added pg_proc entries for all the new functions. Jan	27 years ago
Jan Wieck	b5c4b77283	Added nbtree operator class for NUMERIC ... Jan	27 years ago
Tom Lane	44878506d8	First step in fixing selectivity-estimation code. eqsel and ... neqsel now behave as per my suggestions in pghackers a few days ago. selectivity for < > <= >= should work OK for integral types as well, but still need work for nonintegral types. Since these routines have never actually executed before :-(, this may result in some significant changes in the optimizer's choices of execution plans. Let me know if you see any serious misbehavior. CAUTION: THESE CHANGES REQUIRE INITDB. pg_statistic table has changed.	27 years ago

Bruce Momjian	210055ad61	here are some patches for 6.5.0 which I already submitted but have never ... been applied. The patches are in the .tar.gz attachment at the end: varchar-array.patch this patch adds support for arrays of bpchar() and varchar(), which where always missing from postgres. These datatypes can be used to replace the _char4, _char8, etc., which were dropped some time ago. block-size.patch this patch fixes many errors in the parser and other program which happen with very large query statements (> 8K) when using a page size larger than 8192. This patch is needed if you want to submit queries larger than 8K. Postgres supports tuples up to 32K but you can't insert them because you can't submit queries larger than 8K. My patch fixes this problem. The patch also replaces all the occurrences of `8192' and `1<<13' in the sources with the proper constants defined in include files. You should now never find 8192 hardwired in C code, just to make code clearer. -- Massimo Dal Zotto	27 years ago
Tom Lane	4a9c239063	Fix brain death in !!= operator ... it's still pretty bogus ... but at least now it does what it's supposed to do ...	27 years ago
Bruce Momjian	c10e6bcbed	Attempting to insert a value of 'now' into a datetime type ... results in a bogus datetime value under AlphaLinux. (Note that the link to submit a port-specific bug on your website is broken) -Test Case: ---------- testdb=> create table dttest (dt datetime); testdb=> insert into dttest values ('now'); -------------------------------------------------------------------------- Solution: --------- The basic problem is the typedefs of AbsoluteTime and RelativeTime, which are both 'int32'. These types appear to be used synonymously with the 'time_t' type, which on AlphaLinux is typedef'd as a 'long int', which is 64-bits (not 32). The solution included here fixes the datetime type (it now passes the regression test), but does not pass the absolute and relative time regression tests. Presumably, a more thorough investigation of how these types are used is warranted. The included patch is from the v6.3.2 source, but can be applied to the v6.4.2 source. Please note that there is also a RedHat-specific patch distributed with the PostgreSQL source package from RedHat that was applied first. Rich Edwards	27 years ago
Bruce Momjian	817a3e6d39	Enclosed below I have a patch to allow a btree index on the int8 type. ... I would like some feedback on what the hash function for the int8 hash function in the ./backend/access/hash/hashfunc.c should return. Also, could someone (maybe Tomas Lockhart?) look-over the patch and make sure the system table entries are correct? I've tried to research them as much as I could, but some of them are still not clear to me. Thanks, -Ryan	27 years ago

Bruce Momjian	8849655d24	I agree. I think, though, that the best argument presented in the ... debate was from Paul Vixie, who wanted INET to be the name covering both IPV4 and IPV6. The following kit makes the needed changes: Tom Ivar Helbekkmo	28 years ago

Bruce Momjian	7971539020	heap_fetch requires buffer pointer, must be released; heap_getnext ... no longer returns buffer pointer, can be gotten from scan; descriptor; bootstrap can create multi-key indexes; pg_procname index now is multi-key index; oidint2, oidint4, oidname are gone (must be removed from regression tests); use System Cache rather than sequential scan in many places; heap_modifytuple no longer takes buffer parameter; remove unused buffer parameter in a few other functions; oid8 is not index-able; remove some use of single-character variable names; cleanup Buffer variables usage and scan descriptor looping; cleaned up allocation and freeing of tuples; 18k lines of diff;	28 years ago
