Tom Lane	a4d82dd4b4	Adjust API of expression_tree_mutator and query_tree_mutator to ... simplify callers. It turns out the common case is that the caller does want to recurse into sub-queries, so push support for that into these subroutines.	23 years ago
Tom Lane	227a404cf4	Add code to print information about a detected deadlock cycle. The ... printed data is comparable to what you could read in the pg_locks view, were you fortunate enough to have been looking at it at the right time.	23 years ago
Tom Lane	136828c699	Ooops, didn't cut-and-paste quite enough code from ResolveNew; ... with result that flatten_join_alias_vars failed to descend into subselects.	23 years ago
Tom Lane	57ce0f84f2	Fix bogus formatting of DROP DATABASE command, per Christopher Kings-Lynne.	23 years ago
Tom Lane	cb23b8415b	Repair an embarrassingly large number of alphabetization mistakes in the ... datetime token tables. Even more embarrassing, the regression tests revealed some of the problems --- but evidently the bogus output wasn't questioned. Add code to postmaster startup to directly check the tables for correct ordering, in hopes of not being embarrassed like this again.	23 years ago
Peter Eisentraut	828822bc96	Add remaining documentation tables to information schema.	23 years ago
Tom Lane	cde9f852e0	Now that switch_outer processing no longer relies on being run after ... join_references(), it's practical to consolidate all join_references() processing into the set_plan_references traversal in setrefs.c. This seems considerably cleaner than the old way where we did it for join quals in createplan.c and for targetlists in setrefs.c.	23 years ago
Bruce Momjian	606d4f7b38	Oops, put back changes. Those were Peter's, not mine.	23 years ago

Bruce Momjian	20803fa3d2	Update shared_buffer comment in postgresql.conf.	23 years ago
Bruce Momjian	4b874036c2	Back out ORDER BY addition to Inet, for Tom.	23 years ago
Tom Lane	de97072e3c	Allow merge and hash joins to occur on arbitrary expressions (anything not ... containing a volatile function), rather than only on 'Var = Var' clauses as before. This makes it practical to do flatten_join_alias_vars at the start of planning, which in turn eliminates a bunch of klugery inside the planner to deal with alias vars. As a free side effect, we now detect implied equality of non-Var expressions; for example in SELECT ... WHERE a.x = b.y and b.y = 42 we will deduce a.x = 42 and use that as a restriction qual on a. Also, we can remove the restriction introduced 12/5/02 to prevent pullup of subqueries whose targetlists contain sublinks. Still TODO: make statistical estimation routines in selfuncs.c and costsize.c smarter about expressions that are more complex than plain Vars. The need for this is considerably greater now that we have to be able to estimate the suitability of merge and hash join techniques on such expressions.	23 years ago

Bruce Momjian	ecbd8daaac	Add ORDER BY for inet regression, pointed out by Rod Taylor.	23 years ago
Peter Eisentraut	2160c9177d	Add sql_features table to information schema. Generate the features list ... in the documentation from that same data.	23 years ago

Barry Lind	56e6436c3a	Bumped up build number to 200	23 years ago
Barry Lind	feefc329bd	Patch from Florian Wunderlich to correctly support java Timestamps. Previously ... the code would only capture milliseconds where as both postgres and the java Timestamp object support greater resolution. Also fixed a bug reported by Rhett Sutphin where the last digit of the fractional seconds was lost when using timestamp without time zone Modified Files: jdbc/org/postgresql/jdbc1/AbstractJdbc1ResultSet.java jdbc/org/postgresql/test/jdbc2/TimestampTest.java	23 years ago
Barry Lind	9db065ba56	Patch from Aaron Mulder to have pooled connections implement PGConnection ... Modified Files: jdbc/org/postgresql/jdbc2/optional/PooledConnectionImpl.java jdbc/org/postgresql/test/jdbc2/optional/BaseDataSourceTest.java	23 years ago
Barry Lind	88e524063a	Patch from Kris Jurka to improve the performance of getImportedKeys(). ... Use explicit joins to avoid using the genetic query optimizer. Also fixed a regression test that was failing to compile. This change also cleans up how key names are reported as per: A change to the value of the FK_NAME column. Currently the returned value is the triggers arguments which look like "<unnamed>\000t2\000t1\000UNSPECIFIED\000a\000a\000" This was required for server versions < 7.3 when a user did not supply constraint names. Every constraint was named "<unnamed>" . 7.3 has enforced unique constraint names per table so unnamed foreign keys will have different names "$1", "$2" and so on. I've used logic along the lines of the following to preserve the unique names in the original scheme, but allow people who go to the trouble of naming their constraints to see them: if (triggerargs.startsWith("<unnamed>")) { fkname = [the whole ugly trigger args name originally used]; } else { fkname = [the actual fk name]; } Modified Files: jdbc/org/postgresql/jdbc1/AbstractJdbc1DatabaseMetaData.java jdbc/org/postgresql/test/jdbc2/optional/ConnectionPoolTest.java	23 years ago

Tom Lane	56e1aab286	Reconsider mechanism for marking sub-selects that are at top level of ... a qualification clause (and hence can get away with being sloppy about distinguishing FALSE from UNKNOWN). We need to know this in subselect.c; marking the subplans in setrefs.c is too late.	23 years ago

Tom Lane	8ac6d952cf	Cause planner to account for evaluation costs in targetlists and ... HAVING quals. Normally this is an insignificant effect --- but it will not be insignificant when these clauses contain sub-selects. The added costs cannot affect the planning of the query containing them, but they might have an impact when the query is a sub-query of a larger one.	23 years ago
Tom Lane	d1686b42ab	Recent changes in sublink representation require exprType() to accept ... SubPlan nodes, else explaining queries containing sublinks may fail.	23 years ago
Tom Lane	d4ce5a4f4c	Revise cost_qual_eval() to compute both startup (one-time) and per-tuple ... costs for expression evaluation, not only per-tuple cost as before. This extension is needed in order to deal realistically with hashed or materialized sub-selects.	23 years ago
