      Support alternate storage scheme of 64-bit integer for date/time types. · 547df0cc
      Thomas G. Lockhart 提交于
       Use "--enable-integer-datetimes" in configuration to use this rather
       than the original float8 storage. I would recommend the integer-based
       storage for any platform on which it is available. We perhaps should
       make this the default for the production release.
      Change timezone(timestamptz) results to return timestamp rather than
       a character string. Formerly, we didn't have a way to represent
       timestamps with an explicit time zone other than freezing the info into
       a string. Now, we can reasonably omit the explicit time zone from the
       result and return a timestamp with values appropriate for the specified
       time zone. Much cleaner, and if you need the time zone in the result
       you can put it into a character string pretty easily anyway.
      Allow fractional seconds in date/time types even for dates prior to 1BC.
      Limit timestamp data types to 6 decimal places of precision. Just right
       for a micro-second storage of int8 date/time types, and reduces the
       number of places ad-hoc rounding was occuring for the float8-based types.
      Use lookup tables for precision/rounding calculations for timestamp and
       interval types.  Formerly used pow() to calculate the desired value but
       with a more limited range there is no reason to not type in a lookup
       table. Should be *much* better performance, though formerly there were
       some optimizations to help minimize the number of times pow() was called.
      Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option
       "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED.
      Add explicit date/interval operators and functions for addition and
       subtraction. Formerly relied on implicit type promotion from date to
       timestamp with time zone.
      Change timezone conversion functions for the timetz type from "timetz()"
       to "timezone()". This is consistant with other time zone coersion
       functions for other types.
      Bump the catalog version to 200204201.
      Fix up regression tests to reflect changes in fractional seconds
       representation for date/times in BC eras.
      All regression tests pass on my Linux box.

      Make WITHOUT TIME ZONE the default for TIMESTAMP and TIME data types. · 37cfb040
      Thomas G. Lockhart 提交于
       This is a big change from past behavior, but the last release was
       designed to handle this correctly for dump/restore upgrades.
      Fix up handling of SET value arguments. Allow lists for most options at
       least at the parser level; multiple values may be rejected at the
       command processor of course.
      Allow more variations on values for SET commands, including integer and
       float values where formerly stringy fields were required.
      Check precision specification for date/time fields against the true
       precision range allowed by the data types. Especially useful with the
       new int8-based storage for these types, where precision is fixed and
       predictable.
      Stub out a basic CREATE ASSERTION per SQL9x. Does not do anything (yet) but
       should be augmented as appropriate.
      Minor fixups in braces and tabbing.

      Allow more choices for style of value in various SET commands. Formerly, · e53f94ad
      Thomas G. Lockhart 提交于
       most required a stringy syntax in the parser; now integers and floats
       can (or should) be handled. There is at least one cheesy error message
       mentioning sending mail to me if there are problems; should be changed
       prior to release.
      Allow lists of values from the parser in more cases. If multiple arguments
       were not allowed previously, they probably are not allowed now, but at
       least the data structures being passed around are more consistant across
       more cases.
