Tom Lane	a067b50470	Get rid of minus zero in box regression test. Commit `acdf2a8b` added a test case involving minus zero as a box endpoint. This is not very portable, as evidenced by the several older buildfarm members that are failing on the test because they print minus zero as just "0". If there were any significant reason to test this behavior, we could consider carrying a separate expected-file; but it doesn't look to me like there's adequate justification to accept such a maintenance burden. Just change the test to use plain zero, instead.	10 years ago
Teodor Sigaev	acdf2a8b37	Introduce SP-GiST operator class over box. Patch implements quad-tree over boxes, naive approach of 2D quad tree will not work for any non-point objects because splitting space on node is not efficient. The idea of pathc is treating 2D boxes as 4D points, so, object will not overlap (in 4D space). The performance tests reveal that this technique especially beneficial with too much overlapping objects, so called "spaghetti data".

Peter Eisentraut	3f11971916	Remove extra newlines at end and beginning of files, add missing newlines at end of files.	16 years ago
Tom Lane	ba920e1c91	Rename contains/contained-by operators to @> and <@, per discussion that agreed these symbols are less easily confused. I made new pg_operator entries (with new OIDs) for the old names, so as to provide backward compatibility while making it pretty easy to remove the old names in some future release cycle. This commit only touches the core datatypes, contrib will be fixed separately.	20 years ago
Neil Conway	f5ab0a14ea	Add a "USING" clause to DELETE, which is equivalent to the FROM clause in UPDATE. We also now issue a NOTICE if a query has _any_ implicit range table entries -- in the past, we would only warn about implicit RTEs in SELECTs with at least one explicit RTE. As a result of the warning change, 25 of the regression tests had to be updated. I also took the opportunity to remove some bogus whitespace differences between some of the float4 and float8 variants. I believe I have correctly updated all the platform-specific variants, but let me know if that's not the case. Original patch for DELETE ... USING from Euler Taveira de Oliveira, reworked by Neil Conway.	21 years ago
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
Thomas G. Lockhart	4c4e68dccc	Clean up format of tests. Remove older "::" type coersion syntax in favor of extended SQL92 style. Include a few new tests for datetime/timespan arithmetic.	26 years ago
Thomas G. Lockhart	83b8cf5b6b	Add inter-type regression tests for geometry, date/time, and numbers. Add regression tests for circles, line segments, and paths. Modify regression tests to allow GEQ optimizer (order results).	29 years ago
Marc G. Fournier	3451abf632	Make these self-contained tests...they are testing types, so the tables that are created should only exist as long as the test requires them... things are just toooooo spread around	29 years ago
Marc G. Fournier	d108a31082	There are the broken out 'sql' queries from queries.source tests allows us to have a 'for...done' loop inside of regress.sh for both doing the tests, and determining fail/ok results	29 years ago
