5ab15591d9 eqjoinsel's logic for case where MCV lists are not present should 
account for NULLs; in hindsight this is obvious since the code for
the MCV-lists case would reduce to this when there are zero entries
in both lists.  Per example from Alec Mitchell.

0851e12244 Reorganize clog's error reporting so that PANIC on clog I/O error can 
be reduced to a plain ERROR.  Should make it at least a little less
painful to deal with data-corruption problems.

da2060e5fd Remove premature attempt to constant-fold type coercion expressions. 
While usually safe, this fails if the coercion function needs the
query snapshot to be set already.  Per example from Nigel Andrews.

a6554df4f7 In an effort to reduce the total number of chapters, combine the small 
chapters on extending types, operators, and aggregates into the extending
functions chapter.  Move the information on how to call table functions
into the queries chapter.  Remove some outdated information that is
already present in a better form in other parts of the documentation.

730840c9b6 First phase of work on array improvements. ARRAY[x,y,z] constructor 
expressions, ARRAY(sub-SELECT) expressions, some array functions.
Polymorphic functions using ANYARRAY/ANYELEMENT argument and return
types.  Some regression tests in place, documentation is lacking.
Joe Conway, with some kibitzing from Tom Lane.

cd203f3395 Avoid primary key lookup (and lock) if foreign key does not change 
on UPDATE.

This get's rid of the long standing annoyance that updating a row
that has foreign keys locks all the referenced rows even if the
foreign key values do not change.

The trick is to actually do a check identical to NO ACTION after an
eventually done UPDATE in the SET DEFAULT case. Since a SET DEFAULT
operation should have moved referencing rows to a new "home", a following
NO ACTION check can only fail if the column defaults of the referencing
table resulted in the key we actually deleted. Thanks to Stephan.

a385186ff7 Remove zero_damaged_pages from postgresql.conf.sample; the only way to 
find out about it is to read the documentation that tells you how
dangerous it is.  Add default_transaction_read_only to documentation;
seems to have been overlooked in patch that added read-only transactions.
Clean up check_guc comparison script, which has been suffering bit rot.
