Tom Lane 4f44aa04b5 Major overhaul of large-object implementation, by Denis Perchine with 
kibitzing from Tom Lane.  Large objects are now all stored in a single
system relation "pg_largeobject" --- no more xinv or xinx files, no more
relkind 'l'.  This should offer substantial performance improvement for
large numbers of LOs, since there won't be directory bloat anymore.
It'll also fix problems like running out of locktable space when you
access thousands of LOs in one transaction.
Also clean up cruft in read/write routines.  LOs with "holes" in them
(never-written byte ranges) now work just like Unix files with holes do:
a hole reads as zeroes but doesn't occupy storage space.
INITDB forced!

The PostgreSQL contrib tree
~~~~~~~~~~~~~~~~~~~~~~~~~~~

This subtree contains tools, modules, and examples that are not
maintained as part of the core PostgreSQL system, mainly because
they only address a limited audience or are too inelegant to be
sold as an official feature.  That, however, does not preclude
their usefulness.

Each subdirectory contains a README file with information about the
module.  Most items can be built with `gmake all' and installed
with `gmake install' in the usual fashion, after you have run the
`configure' script in the top-level directory.  Some directories
supply new user-defined functions, operators, or types.  After you
have installed the files you need to register the new entities in
the database system by running the commands in the supplied .sql
file.  For example,

	$ psql -d dbname -f module.sql

See the PostgreSQL documentation for more information about this
procedure.
