large objects. Dump all these in pg_dump; also add code to pg_dump
user-defined conversions. Make psql's large object code rely on
the backend for inserting/deleting LOB comments, instead of trying to
hack pg_description directly. Documentation and regression tests added.

This first part of the background writer does no syncing at all.
It's only purpose is to keep the LRU heads clean so that regular
backends seldom to never have to call write().

which had been unintentionally broken by recent changes to tighten up the
DateStyle rules for all-numeric date input. Add documentation and
regression tests for this, too.
data directory. Also fix handling of error conditions associated with
data directory checking step (can't use a boolean to distinguish four
possible result states...)
of option switches for backend, fix handling of COPY from data files so
that we won't have the newline-after-\. issue back again, add back some
comments and printouts lost from the shell script, etc. Still needs work
for error handling; in particular the shell version worked much more
nicely for the case of a postgres executable that fails on invocation.
pghackers proposal of 8-Nov. All the existing cross-type comparison
operators (int2/int4/int8 and float4/float8) have appropriate support.
The original proposal of storing the right-hand-side datatype as part of
the primary key for pg_amop and pg_amproc got modified a bit in the event;
it is easier to store zero as the 'default' case and only store a nonzero
when the operator is actually cross-type. Along the way, remove the
long-since-defunct bigbox_ops operator class.
Remove the 'strategy map' code, which was a large amount of mechanism
that no longer had any use except reverse-mapping from procedure OID to
strategy number. Passing the strategy number to the index AM in the
first place is simpler and faster.
This is a preliminary step in planned support for cross-datatype index
operations. I'm committing it now since the ScanKeyEntryInitialize()
API change touches quite a lot of files, and I want to commit those
changes before the tree drifts under me.
