  • e0bb171960 Fix ALTER TABLE to check pre-existing NOT NULL constraints when rewriting a table. Otherwise a USING clause that yields NULL can leave the table violating its constraint (possibly there are other cases too). Per report from Alexander Pravking. Tom Lane 2006-07-10 22:10:47 +00:00

  • b7b78d24f7 Code review for FILLFACTOR patch. Change WITH grammar as per earlier discussion (including making def_arg allow reserved words), add missed opt_definition for UNIQUE case. Put the reloptions support code in a less random place (I chose to make a new file access/common/reloptions.c). Eliminate header inclusion creep. Make the index options functions safely user-callable (seems like client apps might like to be able to test validity of options before trying to make an index). Reduce overhead for normal case with no options by allowing rd_options to be NULL. Fix some unmaintainably klugy code, including getting rid of Natts_pg_class_fixed at long last. Some stylistic cleanup too, and pay attention to keeping comments in sync with code. Tom Lane 2006-07-03 22:45:41 +00:00

  • 08ccdf020e Fix oversight in planning for multiple indexscans driven by ScalarArrayOpExpr index quals: we were estimating the right total number of rows returned, but treating the index-access part of the cost as if a single scan were fetching that many consecutive index tuples. Actually we should treat it as a multiple indexscan, and if there are enough of 'em the Mackert-Lohman discount should kick in. Tom Lane 2006-07-01 22:07:23 +00:00
  • cffd89ca73 Revise the planner's handling of "pseudoconstant" WHERE clauses, that is clauses containing no variables and no volatile functions. Such a clause can be used as a one-time qual in a gating Result plan node, to suppress plan execution entirely when it is false. Even when the clause is true, putting it in a gating node wins by avoiding repeated evaluation of the clause. In previous PG releases, query_planner() would do this for pseudoconstant clauses appearing at the top level of the jointree, but there was no ability to generate a gating Result deeper in the plan tree. To fix it, get rid of the special case in query_planner(), and instead process pseudoconstant clauses through the normal RestrictInfo qual distribution mechanism. When a pseudoconstant clause is found attached to a path node in create_plan(), pull it out and generate a gating Result at that point. This requires special-casing pseudoconstants in selectivity estimation and cost_qual_eval, but on the whole it's pretty clean. It probably even makes the planner a bit faster than before for the normal case of no pseudoconstants, since removing pull_constant_clauses saves one useless traversal of the qual tree. Per gripe from Phil Frost. Tom Lane 2006-07-01 18:38:33 +00:00

  • 51e400c9c6 Remove the separate 'stats buffer' process, letting backend stats messages be delivered directly to the collector process. The extra process context swaps required to transfer data through the buffer process seem to outweigh any value the buffering might have. Per recent discussion and tests. I modified Bruce's draft patch to use poll() rather than select() where available (this makes a noticeable difference on my system), and fixed up the EXEC_BACKEND case. Tom Lane 2006-06-29 20:00:08 +00:00
  • cd4609e2a4 Change TRUNCATE's method for searching for foreign-key references so that the order in which it visits tables is not dependent on the physical order of pg_constraint entries, and neither are the error messages it gives. This should correct recently-noticed instability in regression tests. Tom Lane 2006-06-29 16:07:29 +00:00

  • 1c1ecd5124 Improve planner estimates for size of tuple hash tables. Tom Lane 2006-06-28 20:04:38 +00:00
  • 485375a1c9 Fix hash aggregation to suppress unneeded columns from being stored in tuple hash table entries. This addresses the problem previously noted that use of a 'physical tlist' in the input scan node could bloat the hash table entries far beyond what the planner expects. It's a better answer than my previous thought of undoing the physical tlist optimization, because we can also remove columns that are needed to compute the aggregate functions but aren't part of the grouping column set.

  • 3c71244b74 Put #ifdef NOT_USED around posix_fadvise call.

  • 33b4ad66c9 Revert patch, doesn't do what it should: Bruce Momjian 2006-06-27 18:35:05 +00:00
  • cdd5178c69 Extend the MinimalTuple concept to tuplesort.c, thereby reducing the per-tuple space overhead for sorts in memory. I chose to replace the previous patch that tried to write out the bare minimum amount of data when sorting on disk; instead, just dump the MinimalTuples as-is. This wastes 3 to 10 bytes per tuple depending on architecture and null-bitmap length, but the simplification in the writetup/readtup routines seems worth it. Tom Lane 2006-06-27 16:53:02 +00:00

  • ca0d2197ca Change the row constructor syntax (ROW(...)) so that list elements foo.* will be expanded to a list of their member fields, rather than creating a nested rowtype field as formerly. (The old behavior is still available by omitting '.*'.) This syntax is not allowed by the SQL spec AFAICS, so changing its behavior doesn't violate the spec. The new behavior is substantially more useful since it allows, for example, triggers to check for data changes with 'if row(new.*) is distinct from row(old.*)'. Per my recent proposal.
