Tom Lane	8e35bbd133	Remove fixed-size literal buffer from scan.l, and repair ... boundary-condition bug in myinput() which caused flex scanner to fail on tokens larger than a bufferload. Turns out flex doesn't want null- terminated input ... and if it gives you a 1-character buffer, you'd better supply a character, not a null, lest you be thought to be reporting end of input.	27 years ago

Tom Lane	3d5079c174	Except_Intersect_Rewrite() forgot to move LIMIT info to new ... topmost SELECT node after rearranging query tree.	27 years ago
Tom Lane	e1c76c2533	Change fd.c so that temp files are closed and deleted at ... proc_exit time. I discovered that if the frontend closes the connection when you're inside a transaction block, there is nothing ensuring that temp files go away ... I wonder whether proc_exit ought to try to do an explicit transaction abort?	27 years ago
Tom Lane	887afac1f5	Remove now-dead sort modules.	27 years ago
Tom Lane	26c48b5e8c	Final stage of psort reconstruction work: replace psort.c with ... a generalized module 'tuplesort.c' that can sort either HeapTuples or IndexTuples, and is not tied to execution of a Sort node. Clean up memory leakages in sorting, and replace nbtsort.c's private implementation of mergesorting with calls to tuplesort.c.	27 years ago

Tom Lane	957146dcec	Second phase of psort reconstruction project: add bookkeeping logic to ... recycle storage within sort temp file on a block-by-block basis. This reduces peak disk usage to essentially just the volume of data being sorted, whereas it had been about 4x the data volume before.	27 years ago

Bruce Momjian	7acc237744	This patch implements ORACLE's COMMENT SQL command. ... >From the ORACLE 7 SQL Language Reference Manual: ----------------------------------------------------- COMMENT Purpose: To add a comment about a table, view, snapshot, or column into the data dictionary. Prerequisites: The table, view, or snapshot must be in your own schema or you must have COMMENT ANY TABLE system privilege. Syntax: COMMENT ON [ TABLE table ] | [ COLUMN table.column] IS 'text' You can effectively drop a comment from the database by setting it to the empty string ''. ----------------------------------------------------- Example: COMMENT ON TABLE workorders IS 'Maintains base records for workorder information'; COMMENT ON COLUMN workorders.hours IS 'Number of hours the engineer worked on the task'; to drop a comment: COMMENT ON COLUMN workorders.hours IS ''; The current patch will simply perform the insert into pg_description, as per the TODO. And, of course, when the table is dropped, any comments relating to it or any of its attributes are also dropped. I haven't looked at the ODBC source yet, but I do know from an ODBC client standpoint that the standard does support the notion of table and column comments. Hopefully the ODBC driver is already fetching these values from pg_description, but if not, it should be trivial. Hope this makes the grade, Mike Mascari (mascarim@yahoo.com)	27 years ago

Tom Lane	db3c4c3a2d	Split 'BufFile' routines out of fd.c into a new module, buffile.c. Extend ... BufFile so that it handles multi-segment temporary files transparently. This allows sorts and hashes to work with data exceeding 2Gig (or whatever the local limit on file size is). Change psort.c to use relative seeks instead of absolute seeks for backwards scanning, so that it won't fail when the data volume exceeds 2Gig.	27 years ago
Bruce Momjian	c3ac9f07b7	Hi, ... I have changed a bit the makefiles for the win32 port - the *.def files (created when building shared libraries) are now clean from Makefile.shlib. I have also removed "-g" from CFLAGS in the "cygwin32" template - it can be enabled when running configure. Dan	27 years ago

Bruce Momjian	e3dd4942c7	Update for NUMERIC/DECIMAL data type.	27 years ago
Bruce Momjian	7ee7ee1398	BLOBs containing NUL characters (ASCII 0) can be written to the ... database, but they get truncated at the first NUL by lo_read when they are read back. The reason for this is that lo_read in Pg.xs is using the default: OUTPUT: RETVAL buf which uses C's strlen() to work out the length of the scalar. The code ought to read something more like: OUTPUT: RETVAL buf sv_setpvn((SV*)ST(2), buf, RETVAL); I am not sure if this needs to be done on both lo_read methods in this file, but I changed both and have not since had any problems with truncated BLOBs.

Bruce Momjian	c6411605e1	I have created a small patch that makes possible to compile pgsql on newer ... Cygwin snapshots (tested on 990115 which is recommended to use - it fixes some errors in B20.1) And I have another patch for including <sys/ipc.h> before <sys/sem.h> in backend/storage/lmgr/proc.c - it is required due the design of cygipc headers Dan	27 years ago
