Bruce Momjian	4893eadc3c	Remove tabs from SGML file.	19 years ago
Andrew Dunstan	55613bf9cd	Close previously open holes for invalidly encoded data to enter the database via builtin functions, as recently discussed on -hackers. chr() now returns a character in the database encoding. For UTF8 encoded databases the argument is treated as a Unicode code point. For other multi-byte encodings the argument must designate a strict ascii character, or an error is raised, as is also the case if the argument is 0. ascii() is adjusted so that it remains the inverse of chr(). The two argument form of convert() is gone, and the three argument form now takes a bytea first argument and returns a bytea. To cover this loss three new functions are introduced: . convert_from(bytea, name) returns text - converts the first argument from the named encoding to the database encoding . convert_to(text, name) returns bytea - converts the first argument from the database encoding to the named encoding . length(bytea, name) returns int - gives the length of the first argument in characters in the named encoding	19 years ago

Bruce Momjian	851745a97a	Remove extra tab in postgresql.conf	19 years ago
Tom Lane	039dc49d55	Remove Assert(BgWriterShmem != NULL), which is rather pointless since we'd dump core anyway immediately afterward if it were null; and it seems to confuse some versions of icc into generating bad code. Per report from Sergey Koposov. Patched in HEAD only, for the moment, since this is only likely to affect developers.	19 years ago
Tom Lane	22d98e7934	Fix overflow in extract(epoch from interval) for intervals exceeding 68 years. Seems to have been introduced in 8.1 by careless SECS_PER_DAY search-and-replace.	19 years ago
Tom Lane	e92da1a9d1	Update release notes for last-minute fix.	19 years ago
Tom Lane	43b0c9182f	Fix aboriginal mistake in lazy VACUUM's code for truncating away no-longer-needed pages at the end of a table. We thought we could throw away pages containing HEAPTUPLE_DEAD tuples; but this is not so, because such tuples very likely have index entries pointing at them, and we wouldn't have removed the index entries. The problem only emerges in a somewhat unlikely race condition: the dead tuples have to have been inserted by a transaction that later aborted, and this has to have happened between VACUUM's initial scan of the page and then rechecking it for empty in count_nondeletable_pages. But that timespan will include an index-cleaning pass, so it's not all that hard to hit. This seems to explain a couple of previously unsolved bug reports.	19 years ago

Bruce Momjian	ae36e0d589	Update tsearch include location in example. Oleg.	19 years ago
Bruce Momjian	17aae41afd	Add tsearch tab completion support: * adds a few missing words to some commands (like adding GIN as a valid index type or OWNED BY for ALTER SEQUENCE,...) * support for ALTER TABLE foo ENABLE/DISABLE REPLICA TRIGGER/RULE * autocomplete CREATE DATABASE foo TEMPLATE (mostly done to prevent conflicts with the TEMPLATE keyword for text search) * support for ALTER/CREATE/DROP TEXT SEARCH as well as COMMENT ON TEXT SEARCH and the corresponding psql backslash commands. This proved a little more difficult than expected due to the fact that words_after_create[] is used for two purposes - one is to provide a list of words that follow immediatly after CREATE (or DROP) and the other purpose is to use it for autocompleting anywhere in the statement if the word in that struct is found with a query. Since TEXT SEARCH CONFIGURATION\|DICTIONARY\|TEMPLATE\|PARSER results in 3 words instead of one (as all the other words in that list are) I added a flag to the struct to tell create_command_generator() to skip that entry for autocompleting immediatly after CREATE which feels like a dirty hack (but that holds true for a lot of code in tab-complete.c).

Alvaro Herrera	945ba50dc3	Fix a memory leak in the autovacuum launcher code. Noted by Darcy Buskermolen, who reported it privately to me.	19 years ago
Tom Lane	6889303531	Redefine the lp_flags field of item pointers as having four states, rather than two independent bits (one of which was never used in heap pages anyway, or at least hadn't been in a very long time). This gives us flexibility to add the HOT notions of redirected and dead item pointers without requiring anything so klugy as magic values of lp_off and lp_len. The state values are chosen so that for the states currently in use (pre-HOT) there is no change in the physical representation.	19 years ago
Andrew Dunstan	eb0a7735ba	Perform post-escaping encoding validity checks on SQL literals and COPY input so that invalidly encoded data cannot enter the database by these means.	19 years ago

Tom Lane	861f7357b9	Give ICC its preferred, documented form of the no-strict-aliasing switch, viz '-fno-alias'. Since we have a separate code path here anyway, it's just as easy to cooperate.	19 years ago

Bruce Momjian	da7192d1d4	Stamp	19 years ago
Tom Lane	f181f9e1e4	Make sure that open hash table scans are cleaned up when bgwriter tries to recover from elog(ERROR). Problem was created by introduction of hash seq search tracking awhile back, and affects all branches that have bgwriter; in HEAD the disease has snuck into autovacuum and walwriter too. (Not sure that the latter two use hash_seq_search at the moment, but surely they might someday.) Per report from Sergey Koposov.	19 years ago
Tom Lane	5cf785a4de	Include hash table name in all the internal-error elog messages in dynahash.c. Sergey Koposov's current open problem shows the possible usefulness of this, and it doesn't add much code.	19 years ago
