Thomas G. Lockhart	6456810078	Implement column aliases on views "CREATE VIEW name (collist)". ... Implement TIME WITH TIME ZONE type (timetz internal type). Remap length() for character strings to CHAR_LENGTH() for SQL92 and to remove the ambiguity with geometric length() functions. Keep length() for character strings for backward compatibility. Shrink stored views by removing internal column name list from visible rte. Implement min(), max() for time and timetz data types. Implement conversion of TIME to INTERVAL. Implement abs(), mod(), fac() for the int8 data type. Rename some math functions to generic names: round(), sqrt(), cbrt(), pow(), etc. Rename NUMERIC power() function to pow(). Fix int2 factorial to calculate result in int4. Enhance the Oracle compatibility function translate() to work with string arguments (from Edwin Ramirez). Modify pg_proc system table to remove OID holes.	26 years ago
Bruce Momjian	020be62dea	Well, here's the first pass on regression ... tests for the Foreign Key support in 7.0 which was made against a CVS copy from this afternoon. This modifies src/test/regress/sql/run_check.tests src/test/regress/sql/alter_table.sql src/test/regress/expected/alter_table.out src/test/regress/sql/foreign_key.sql src/test/regress/expected/foreign_key.out sszabo@bigpanda.co	26 years ago
Tom Lane	b1577a7c78	New cost model for planning, incorporating a penalty for random page ... accesses versus sequential accesses, a (very crude) estimate of the effects of caching on random page accesses, and cost to evaluate WHERE- clause expressions. Export critical parameters for this model as SET variables. Also, create SET variables for the planner's enable flags (enable_seqscan, enable_indexscan, etc) so that these can be controlled more conveniently than via PGOPTIONS. Planner now estimates both startup cost (cost before retrieving first tuple) and total cost of each path, so it can optimize queries with LIMIT on a reasonable basis by interpolating between these costs. Same facility is a win for EXISTS(...) subqueries and some other cases. Redesign pathkey representation to achieve a major speedup in planning (I saw as much as 5X on a 10-way join); also minor changes in planner to reduce memory consumption by recycling discarded Path nodes and not constructing unnecessary lists. Minor cleanups to display more-plausible costs in some cases in EXPLAIN output. Initdb forced by change in interface to index cost estimation functions.	26 years ago

Bruce Momjian	57b5966405	The following uuencoded, gzip'd file will ... ... 1. Remove the char2, char4, char8 and char16 types from postgresql 2. Change references of char16 to name in the regression tests. 3. Rename the char16.sql regression test to name.sql. 4. Modify the regression test scripts and outputs to match up. Might require new regression.{SYSTEM} files... Darren King	28 years ago
