Bruce Momjian 288579ca71 Update TODO: 
o Allow COPY in CSV mode to control whether a quoted zero-length
          string is treated as NULL

          Currently this is always treated as a zero-length string,
          which generates an error when loading into an integer column

Tom Lane f0828b2fc3 Provide a build-time option to store large relations as single files, rather 
than dividing them into 1GB segments as has been our longtime practice.  This
requires working support for large files in the operating system; at least for
the time being, it won't be the default.

Magnus Hagander 52a8d4f8f7 Implement enum type for guc parameters, and convert a couple of existing 
variables to it. More need to be converted, but I wanted to get this in
before it conflicts with too much...

Other than just centralising the text-to-int conversion for parameters,
this allows the pg_settings view to contain a list of available options
and allows an error hint to show what values are allowed.

Tom Lane d9384a4b73 Remove postmaster.c's check that NBuffers is at least twice MaxBackends. 
With the addition of multiple autovacuum workers, our choices were to delete
the check, document the interaction with autovacuum_max_workers, or complicate
the check to try to hide that interaction.  Since this restriction has never
been adequate to ensure backends can't run out of pinnable buffers, it doesn't
really have enough excuse to live to justify the second or third choices.
Per discussion of a complaint from Andreas Kling (see also bug #3888).

This commit also removes several documentation references to this restriction,
but I'm not sure I got them all.
