When ecpg was rewritten to the new protocol version not all variable types
were corrected. This patch rewrites the code for these types to fix that. It
also fixes the documentation to correctly tell the status of array handling.
Long ago we briefly had an "autocommit" GUC that turned server-side
autocommit on and off. That behavior was removed in 7.4 after concluding
that it broke far too much client-side logic, and making clients cope with
both behaviors was impractical. But the GUC variable was left behind, so
as not to break any client code that might be trying to read its value.
Enough time has now passed that we should remove the GUC completely.
Whatever vestigial backwards-compatibility benefit it had is outweighed by
the risk of confusion for newbies who assume it ought to do something,
as per a recent complaint from Wolfgang Wilhelm.
In passing, adjust what seemed to me a rather confusing documentation
reference to libpq's autocommit behavior. libpq as such knows nothing
about autocommit, so psql is probably what was meant.
ECPG is not supposed to allow and output nested comments in C. These comments
are only allowed in the SQL parts and must not be written into the C file.
Also the different handling of different comments is documented.
This will hopefully be easier to use than pg_config for users who are
already used to the pkg-config interface. It also works better for
multi-arch installations.

This is just like serial and bigserial, except it generates an int2
column rather than int4 or int8.

Since this introduces new refentries that we probably don't want to publish as
man pages, tweak man page stylesheet to omit man pages without manvolnum
element.

Block elements with verbatim formatting (literallayout, programlisting,
screen, synopsis) should be aligned at column 0 independent of the surrounding
SGML, because whitespace is significant, and indenting them creates erratic
whitespace in the output. The CSS stylesheets already take care of indenting
the output.
Assorted markup improvements to go along with it.
