3766e99c41 Add a note that AND and OR are commutative. Apparently, they are not in 
certain other products.

1bd22f55cf Disallow dollar sign in operator names, instead allow it as a non-first 
character in identifiers.  The first change eliminates the current need
to put spaces around parameter references, as in "x<=$2".  The second
change improves compatibility with Oracle and some other RDBMSes.  This
was discussed and agreed to back in January, but did not get done.

e649796f12 Implement outer-level aggregates to conform to the SQL spec, with 
extensions to support our historical behavior.  An aggregate belongs
to the closest query level of any of the variables in its argument,
or the current query level if there are no variables (e.g., COUNT(*)).
The implementation involves adding an agglevelsup field to Aggref,
and treating outer aggregates like outer variables at planning time.

6415ffe7af Not sure how I fixed it the first time, but here's a fix for another

6f4a9fb119 Add User's Guide chapters on Data Definition and Data Manipulation. 
Still needs to be filled with more information, but it gives us a
framework to have a User's Guide with complete coverage of the basic
SQL operations.  Move arrays into data type chapter, inheritance into
DDL chapter (for now).

Make <comment>s show up in the output while the version number ends in
"devel".

Allow cross-book references with entities &cite-user; etc.

 between Postgres and PostgreSQL.

8e0d642c9b Documentation for transaction-ID-wraparound changes. Add a chapter to 
the Admin Guide about routine maintenance tasks.  Currently this only
discusses the various reasons for doing VACUUM, but perhaps it could be
fleshed out with topics like log rotation.

bf56f0759b Make OIDs optional, per discussions in pghackers. WITH OIDS is still the 
default, but OIDS are removed from many system catalogs that don't need them.
Some interesting side effects: TOAST pointers are 20 bytes not 32 now;
pg_description has a three-column key instead of one.

Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey
has some usefulness; pg_dump dumps comments on indexes, rules, and
triggers in a valid order.

initdb forced.

116d2bba7e Add IS UNKNOWN, IS NOT UNKNOWN boolean tests, fix the existing boolean 
tests to return the correct results per SQL9x when given NULL inputs.
Reimplement these tests as well as IS [NOT] NULL to have their own
expression node types, instead of depending on special functions.
From Joe Conway, with a little help from Tom Lane.
