All regression tests pass except for rules.sql (unrelated). Implement "date/time grand unification". Transform datetime and timespan into timestamp and interval. Deprecate datetime and timespan, though translate to new types in gram.y. Transform all datetime and timespan catalog entries into new types. Make "INTERVAL" reserved word allowed as a column identifier in gram.y. Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility routines for all date/time types. date.{h,c} now deals with date, time types. timestamp.{h,c} now deals with timestamp, interval types. nabstime.{h,c} now deals with abstime, reltime, tinterval types.

* IDENTIFICATION
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.

date_le(DateADT dateVal1, DateADT dateVal2)
From: Thomas Lockhart <Thomas.G.Lockhart@jpl.nasa.gov> Subject: [HACKERS] More date time functions Here are some additional patches mostly related to the date and time data types. It includes some type conversion routines to move between the different date types and some other date manipulation routines such as date_part(units,datetime). I noticed Edmund Mergl et al's neat trick for getting function overloading for builtin functions, so started to use that for the date and time stuff. Later, if someone figures out how to get function overloading directly for internal C code, then we can move to that technique. These patches include documentation updates (don't faint!) for the built-in man page. Doesn't yet include mention of timestamp, since I don't know much about it and since it may change a bit to become a _real_ ANSI timestamp which would include parser support for the declaration syntax (what do you think, Dan?). The patches were developed on the 970330 release, but have been rebuilt off of the 970402 release. The first patch below is to get libpq to compile, on my Linux box, but is not related to the rest of the patches and you can choose not to apply that one at this time. Thanks in advance, scrappy!

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.

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).
