* Pass less-unsafe parameters to Darwin's NSLinkModule. While this change ↵Tom Lane2002-10-01
| | | | prevents a backend coredump when loading a broken shlib, it also seems to suppress the error messages that might help debug the problem :-(. Perhaps someone would like to supply a 'linkEdit' hook to get the best of both worlds. But in the meantime, backend crash trumps error reporting.

| | | | | | | | | VACUUM FULL tuple moves. Store full-width t_infomask in WAL, rather than storing low 8 bits and expecting to be able to reconstruct upper bits. While at it, remove redundant t_oid field from WAL headers (the OID, if present, is now recorded in the data portion of the tuple). WAL version number bumped --- this does not force an initdb, you can instead run pg_resetxlog after a clean shutdown of the old postmaster.

| | | | | | | | | ProcKill instead, where we still have a PGPROC with which to wait on LWLocks. This fixes 'can't wait without a PROC structure' failures occasionally seen during backend shutdown (I'm surprised they weren't more frequent, actually). Add an Assert() to LWLockAcquire to help catch any similar mistakes in future. Fix failure to update MyProcPid for standalone backends and pgstat processes.

* Further thinking about heap_mark4update: in HeapTupleSelfUpdated case,Tom Lane2002-09-23
| | | | | | | | | executor should not return the tuple as successfully marked, because in fact it's been deleted. Not clear that this case has ever been seen in practice (I think you'd have to write a SELECT FOR UPDATE that calls a function that deletes some row the SELECT will visit later...) but we should be consistent. Also add comments to several other places that got it right but didn't explain what they were doing.
* Disallow VACUUM, ANALYZE, TRUNCATE on temp tables belonging to otherTom Lane2002-09-23
| | | | | backends. Given that temp tables now store data locally in the local buffer manager, these things are not going to work safely.
* Get rid of bogus use of heap_mark4update in reindex operations (cf.Tom Lane2002-09-23
| | | | | recent bug report). Fix processing of nailed-in-cache indexes; it appears that REINDEX DATABASE has been broken for months :-(.
* In UpdateStats(), don't bother to update the pg_class row if it alreadyTom Lane2002-09-22
| | | | | | | | contains the correct statistics. This is a partial solution for the problem of allowing concurrent CREATE INDEX commands: unless they commit at nearly the same instant, the second one will see the first one's pg_class updates as committed, and won't try to update again, thus avoiding the 'tuple concurrently updated' failure.

* Bring SIMILAR TO and SUBSTRING into some semblance of conformance withTom Lane2002-09-22
| | | | | | | the SQL99 standard. (I'm not sure that the character-class features are quite right, but that can be fixed later.) Document SQL99 and POSIX regexps as being different features; provide variants of SUBSTRING for each.
* Move most of the error checking for foreign-key constraints out ofTom Lane2002-09-22
| | | | | | | | | | | | | | | | | | | | | | parse analysis and into the execution code (in tablecmds.c). This eliminates a lot of unreasonably complex code that needed to have two or more execution paths in case it was dealing with a not-yet-created table column vs. an already-existing one. The execution code is always dealing with already-created tables and so needs only one case. This also eliminates some potential race conditions (the table wasn't locked between parse analysis and execution), makes it easy to fix the gripe about wrong referenced-column names generating a misleading error message, and lets us easily add a dependency from the foreign-key constraint to the unique index that it requires the referenced table to have. (Cf. complaint from Kris Jurka 12-Sep-2002 on pgsql-bugs.) Also, third try at building a deletion mechanism that is not sensitive to the order in which pg_depend entries are visited. Adding the above- mentioned dependency exposed the folly of what dependency.c had been doing: it failed for cases where B depends on C while both auto-depend on A. Dropping A should succeed in this case, but was failing if C happened to be visited before B. It appears the only solution is two separate walks over the dependency tree.

* Provide an upgrade strategy for dump files containing functions declaredTom Lane2002-09-21
| | | | | | | | with OPAQUE. CREATE LANGUAGE, CREATE TRIGGER, and CREATE TYPE will all accept references to functions declared with OPAQUE --- but they will issue a NOTICE, and will modify the function entries in pg_proc to have the preferred type-safe argument or result types instead of OPAQUE. Per recent pghackers discussions.

It's worth noting that they've been broken for a while -- for example, the HashJoin counter increments were broken when you comitted r1.20 of executor/nodeHashJoin.c in May of '99. I've attached a revised patch that doesn't remove the counters (but doesn't increment them either: I'm not sure of all the places where the counter should be incremented). Neil Conway
* Tweak heap.c to refuse attempts to create table columns of standaloneTom Lane2002-09-19

* Department of second thoughts: suppressing implicit casts everywhere inTom Lane2002-09-19
| | | | | | | | ruleutils display is not such a great idea. For arguments of functions and operators I think we'd better keep the historical behavior of showing such casts explicitly, to ensure that the function/operator is reparsed the same way when the rule is reloaded. This also makes the output of EXPLAIN less obscurantist about exactly what's happening.
* Extend pg_cast castimplicit column to a three-way value; this allows usTom Lane2002-09-18
| | | | | | | | | | | | | | | | | | | | | | | | to be flexible about assignment casts without introducing ambiguity in operator/function resolution. Introduce a well-defined promotion hierarchy for numeric datatypes (int2->int4->int8->numeric->float4->float8). Change make_const to initially label numeric literals as int4, int8, or numeric (never float8 anymore). Explicitly mark Func and RelabelType nodes to indicate whether they came from a function call, explicit cast, or implicit cast; use this to do reverse-listing more accurately and without so many heuristics. Explicit casts to char, varchar, bit, varbit will truncate or pad without raising an error (the pre-7.2 behavior), while assigning to a column without any explicit cast will still raise an error for wrong-length data like 7.3. This more nearly follows the SQL spec than 7.2 behavior (we should be reporting a 'completion condition' in the explicit-cast cases, but we have no mechanism for that, so just do silent truncation). Fix some problems with enforcement of typmod for array elements; it didn't work at all in 'UPDATE ... SET array[n] = foo', for example. Provide a generalized array_length_coerce() function to replace the specialized per-array-type functions that used to be needed (and were missing for NUMERIC as well as all the datetime types). Add missing conversions int8<->float4, text<->numeric, oid<->int8. initdb forced.

* Fix for rare race-condition-like failure: if a backend receives SIGUSR2Tom Lane2002-09-16
| | | | | | | | | | (notify/SI-overrun interrupt) while it is in process of doing proc_exit, it is possible for Async_NotifyHandler() to try to start a transaction when one is already running. This leads to Asserts() or worse. I think it may only be possible to occur when frontend synchronization is lost (ie, the elog(FATAL) in SocketBackend() fires), but that is a standard occurrence after error during COPY. In any case, I have seen this failure occur during regression tests, so it is definitely possible.
