While usually safe, this fails if the coercion function needs the
query snapshot to be set already.  Per example from Nigel Andrews.

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  Remove some outdated information that is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.

Polymorphic functions using ANYARRAY/ANYELEMENT argument and return
types.  Some regression tests in place, documentation is lacking.

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.
