Add SQL92 "constants" CURRENT_DATE, CURRENT_TIME, CURRENT_TIMESTAMP,
...
CURRENT_USER.
Add syntax for primary and foreign keys.
Change optional syntax in CREATE INDEX to avoid parsing conflict with
TIMESTAMP WITH TIME ZONE data type (use USING <class> rather than WITH...).
Decouple various categories of data type syntax to allow the most possible
non-ambiguous extensions to SQL92 for column names and labels. This should
make the parser a bit more understandable, or at least easier to find
where and how the data types are handled.
Support syntax for IN and EXISTS clauses with subselects.
Support SQL92 syntax for IS TRUE/IS FALSE/IS NOT TRUE/IS NOT FALSE.

16d65f5c25
Add SQL/92 "constants" current_date, current_time, and current_timestamp.
...
Add SQL/92 types decimal and numeric (temporary for syntax support).
These types need more support in the backend to be really implemented,
and the parser will need to be changed at that time.
Adjust limits on precision parameters for FLOAT(p) to match IEEE-compliant
arithmetic. Perhaps these limits should be processor-specific or obtained
from system include files instead.
