Implement ALTER TABLE .. SET LOGGED / UNLOGGED

Browse Source 
This enables changing permanent (logged) tables to unlogged and
vice-versa.

(Docs for ALTER TABLE / SET TABLESPACE got shuffled in an order that
hopefully makes more sense than the original.)

This form changes the table's tablespace to the specified tablespace and
moves the data file(s) associated with the table to the new tablespace.
Indexes on the table, if any, are not moved; but they can be moved
separately with additional <literal>SET TABLESPACE</literal> commands.
All tables in the current database in a tablespace can be moved by using
the <literal>ALL IN TABLESPACE</literal> form, which will lock all tables
to be moved first and then move each one. This form also supports
<literal>OWNED BY</literal>, which will only move tables owned by the
roles specified. If the <literal>NOWAIT</literal> option is specified
then the command will fail if it is unable to acquire all of the locks
required immediately. Note that system catalogs are not moved by this
command, use <command>ALTER DATABASE</command> or explicit
<command>ALTER TABLE</command> invocations instead if desired. The
<literal>information_schema</literal> relations are not considered part
of the system catalogs and will be moved.
